3 DIRECTORS – 30 YEARS

By Michele Hamill

August 2015 marked the 30th anniversary of the Cornell Library’s conservation program. The traditional gift for a 30th anniversary is a pearl–a gemstone of great beauty, and a term meaning something rare, fine and valuable. We’ve had three gifts– three very fine directors–in our 30 years. Tre Berney, Barbara Berger Eden, and John Dean are each a pearl in their own right.

libescopetb_4It is with great pleasure that we welcome Tre Berney as Director of Digitization and Conservation Services. (Interesting note: Tre hails from Tennessee—whose state gem is the pearl and has the only freshwater pearl cultivation outside of Asia!). This new position was created to provide leadership for both Preservation and Conservation Services and the Digital Media Group.

Tre has been at Cornell for almost 3 years developing and implementing AV digitization workflows to preserve Cornell University’s unique A/V holdings and digital collections. He designed and established a digitization lab to digitize fragile recordings and older legacy formats. Tre and Library colleagues just completed a campus-wide A/V census, the first of its kind at Cornell, as part of a larger A/V initiative partnering the library with Cornell IT to inform a preservation strategy for those formats at imminent risk of degradation, loss and obsolescence. He works closely with Cornell’s Lab of Ornithology, Indiana University, Audio/Visual Preservation Solutions, Syracuse University, UCLA, Columbia and the Library of AV_LabCongress. His work in A/V preservation ensures that Cornell’s unique assets in the form of lectures by faculty, Nobel Laureates, writers and artists, and original source recordings used in research in biology, linguistics and art will be available in the future.

Tre brings a wealth of skills and experiences to this position along with energy, enthusiasm and appreciation for the Library’s collections and the work we do in the conservation program. We’re excited to have Tre leading our program and look forward to collaborating to preserve the many formats that comprise the Library’s collections.

IMG_0715We are also celebrating Barbara Berger Eden and her significant contributions to Cornell Library as she retires this week after 30 years of service. In Barbara’s tenure at Cornell Library, she served several key roles including manager for ambitious microfilming projects, grants officer, and Principal Investigator for successful grants including Save America’s Treasures and the Henry Luce Foundation Chinese Librarian Preservation Training Initiative which strengthens Cornell Library’s relationship with our partner libraries in China by fostering exchange between the academic library communities in the United States and China. Due to Barbara’s efforts, the preservation capability across China has been expanded and important materials for teaching and research are being preserved.

As director of Preservation and Conservation Services since 2005, Barbara led the conservation program through times of great change in academic research libraries with insight, advocacy, and collegiality. As a result, our conservation program has thrived, with dedicated staff with deep expertise and the resources to preserve Library collections in their original format.

Barbara is thBarbara_Twoupe past chair of the Preservation and Reformatting Section of the American Library Association and has been an active member of the Preservation Administrators Group of the New York State Comprehensive Research Libraries. Barbara has served as a wonderful mentor to several Library staff as part of the Library’s Mentoring Program sharing her wide experience, knowledge, and perspective to foster the professional growth of our colleagues. We are deeply appreciative of Barbara’s efforts on our behalf and her thoughtfulness, generosity and support. We wish her a healthy, happy retirement filled with good gardening, family and friends. She will be missed.

deanJohn Dean became Cornell University Library’s first conservation and preservation librarian with the establishment of the program in 1985 and served as director for nearly 20 years before retiring in 2003. John’s background, including a 6-year apprenticeship in bookbinding in his native England, some years spent as journeyman bookbinder, leadership of preservation programs at the Newberry Library and Johns Hopkins University, and two graduate degrees (in library science and in liberal arts with a concentration in the history of science), made him a rare and valuable combination of an effective administrator, master bookbinder, and consummate conservator.

As director of the department, John brought a profound knowledge and deep regard for collections in all formats and instilled an appreciation for fine craftsmanship grounded in professional standards for conservation. He mentored and taught at the local, national and international levels. In 2003 John was the recipient of the prestigious Association for Library Collections & Technical Services Paul Banks & Carolyn Harris Preservation Award for his significant contributions to the field.

John2upJohn remains passionate about preservation and conservation and has endeavored to help institutions around the world through education, training and consultancies in developing countries, such as Laos, Indonesia, Thailand, Vietnam, Myanmar, Java, and Cambodia. He created seminal online tutorials for library conservation and preservation in Southeast Asia, Iraq and the Middle East to give librarians and archivists in these and other countries a set of basic guidelines to inform their preservation efforts. In retirement John continues to assist local institutions care for their book collections. John’s legacy has had a lasting impact on the preservation and conservation field, on Cornell University Library, and on those of us who had the honor and privilege of working with him.

Where will we be in the next 30 years? Undoubtedly, there will be new challenges, formats, and discoveries. Thanks to our 3 distinguished directors, Tre, Barbara, and John, Cornell Library’s conservation program is ready to serve the preservation and conservation needs of the Library well into the future. A sincere thank you to Oya Rieger, Associate University Librarian, for her leadership, vision, and support of our program. Stay connected with us on our Facebook page and on this blog for updates on our many projects and for some pearls of wisdom for caring for library collections.

Many Happy Returns

Michele Hamill

Our new cart for transporting posters, architectural drawings, photographs and maps arrived this week. We have long struggled to transport oversize collection materials safely between the Conservation Lab and the Rare and Manuscripts Collections (RMC). It was 2-person job to navigate through 6 doorways (all different widths), tight turns and 2 elevators with standard flat beds. It wasn’t good for the collections or for our backs!

Thanks to our wonderful colleague Wendy McPhee, conservator for the Toronto Public Library, who alerted us to G.S. Manufacturing in Canada, we now have a custom-built transport cart that safely supports 36” x 48” (and larger) folders in the “U” of the cart, full size cartons on the bottom shelf or additional flat materials, and has a removable lid which can also serve as a work surface.

loadedcart

We have been treating and rehousing several poster collections in the Conservation Lab recently which will now be able to be safely and efficiently returned to RMC with the new cart. WWI and WWII propaganda posters were a visually appealing public campaign to mobilize citizens to the needs of war, unify support, and motivate patriotism. Subjects for the posters included conservation and rationing, recruiting, war bonds, and the perils of careless talk, among others.

The WWII posters arrived in the lab in a tight, flattened bundle. In this state, they were not able to be used by researchers, processed by RMC staff, or safely housed.

13175_BT_DetailWith conservation treatment, these oversize posters (3’ x 4’ and larger) are transformed into a spectacular resource.

BeforeAfter_WarSavings

Unlike the WWI and WWII propaganda posters which were meant for display in public, WWII Newsmaps, produced weekly during the war years, were created for display in military installations to inform and update troops with recent war developments.

The Newsmaps, like the posters, were inaccessible due to being tightly rolled for decades. The Newsmaps on the outside of the roll were badly damaged with numerous tears. As you can imagine, the paper used for weekly Newsmaps in a time of war, was not high-grade and is now brittle and easily torn.

13210_BTAfter cleaning, humidification and flattening, and tear and loss stabilization, the Newsmaps are ready for return to RMC to be made available to researchers.

With 2 more rolls of Newsmaps to treat and rehouse, we’ll look forward to many happy returns to RMC with our new transport cart that fits through all doorways and elevators and drives like a dream!

Luce preservation training, part 2.

by Michele Brown

The next phase of the Luce intern training program has begun. Chen Zhimei from Xiamen University and Zhang Chunmei from Fudan University recently finished four weeks of basic preservation training with our department.

Book repair

The first grant provided training to librarians from 4 institutions in Beijing: the Chinese Agricultural Library, Renmin University, Peking University and Tsinghua University. The new grant targets the preservation needs of  libraries in other areas of mainland China and Taiwan: Fudan University, Xiamen University, Shanghai Jiao Tong University, National Taiwan University, Nanjing Agricultural University, National Chengchi University, Jilin University and Wuhan University.

The purpose of the training is to acquaint librarians in Mainland China and Taiwan with preservation techniques for their growing collections of Western-style bindings. We focus on the repair of circulating books. Other topics covered are: care and handling of library materials, exhibit support construction, simple enclosures, mold mitigation/ remediation, and disaster training.

We began by making blank books using Coptic sewing and case binding construction. Making a blank book is a good way to get acquainted with the materials and construction of many mass-produced, Western style books. We used Canapetta cloth for the spines and Iris Nevins marbled paper for the sides.

Then, we moved on to repairing circulating books. The methods we use have been designed for quick, yet strong repair of books that circulate outside of the library. Depending on the damage, we categorize book repair as “partial”, “half” or “full.”  Here is a slideshow showing full book repair.

We learned from previous interns that libraries in China have a lot of paperback and glue bindings, so we explored stiffening and glue binding techniques.

We rehearsed disaster response and salvage and discussed how to make an effective disaster plan.

During the final week, they met with Michele Hamill and Jill Iacchei to get an overview of how to care for flat materials and photographs. We also visited the Syracuse University preservation department to see how another institution handles book repair.

We concluded  by reviewing materials and vendors for archival supplies. Zhimei and Chunmei made book models with cutaways that showed some of the techniques they learned.

Zhimei and Chunmei returned to China at the beginning of June. They have plans to set up preservation operations in their own libraries. We had a great time and hope to see them again. In September we will have interns from Shanghai Jiao Tong University and the National Taiwan University.

 

 

 

Preservation Week 2015: Ways to save your stuff.

by Michele Brown

Last week, Tre Berney provided an excellent summary of AV preservation and related issues. What about books, papers, photographs and other memorabilia you’d like to save and pass along? Here are some resources to help you preserve  your collections.

First, the Cornell Library Conservation website offers many resources to individuals and libraries.

Our  recently revised Preservation and Conservation tutorial for China, which was developed as part of the Luce grant, provides a broad survey of techniques for the preservation of all types of library materials.

One useful tool for protecting fragile books is the marginal materials (MM) case. The tutorial includes a slideshow that describes how to make this simple, but effective container. Written instructions for this and other techniques are included in our repair guides.

Providing a good environment for your materials is the first step in preserving them. The Image Permanence Institute offers numerous resources on ways to understand and control the environment in your home or institution. Watch the video on the effect of humidity fluctuation on a rare book!

Would you like to download leaflets that advise you on the care of your collection and give recommendations for disaster recovery? The Northeast Document Conservation Center (NEDCC) has a series of  preservation leaflets that cover a wide range of topics.

Finally, the Association for Library Collections and Technical Services (ALCTS) offers a series of  preservation webinars.

These are just a few of the many resources available to help us save our stuff so we can pass it on. Happy Preservation Week 2015!

 

 

Preservation Week 2015 | Audio Visual Preservation

Tre Berney

pw_banner

During the American Library Association’s Preservation Week (April 26-May 2, 2015) libraries all over the country present events, activities, and resources that highlight what we can do, individually and together, to preserve our personal and shared history. To start off Preservation Week 2015, Tre Berney, Multimedia Specialist at Cornell University Library, is sharing his expertise in audio-visual preservation with the following blog post.  Tre designed and established the Library’s digitization lab to digitize fragile recordings and older legacy formats and he is the heading up a campus-wide AV census as part of a larger AV initiative partnering the library with Cornell IT. He works closely with Cornell’s Lab of Ornithology, Indiana University, Audio/Visual Preservation Solutions, Syracuse University, UCLA, Columbia and the Library of Congress. Thank you, Tre, for collaborating with us for Preservation Week 2015! –Michele Hamill

First of all, I’m honored to be a guest on our Library’s Conservation Department blog, as they are a great team doing magical things. When discussing audiovisual preservation and the big issues facing possible catastrophic loss of materials on magnetic media, proper conservation becomes even more important as we chart out solutions that may emerge from our campus-wide AV Preservation Initiative.

Both UNESCO’s Blue Ribbon Task Force publication (Sustainable Economics for a Digital Planet, 2010) and the Library Of Congress are estimating that the vast majority of materials housed on magnetic tapes (cassettes, open-reel audiotape, VHS, etc.) will be lost in the next 10 years due to degradation and playback obsolescence. This includes materials ranging from field recordings of cultural events in dying languages to your own home movies of grandparents or children.

Cornell University Library’s Collection Development Executive Committee has set up a preservation fund (allocated though a grant-based system) awarded to save fragile, unique, and heavily used collections and, due to issues with legacy AV content, a lot of that fund has gone to digitization of AV collections. As an example, I’m currently working on digitizing a large collection of VHS tapes for the Africana Library of unique lectures given at Cornell in the past. Last year, this collection was moved to the annex, as they are the only copies in existence and are no longer in circulation.

IMG_20150220_143557 copy

While preservation and digitization is key to older formats, it’s also incredibly challenging for digital formats as well. Digital content, while often easier to use and access in a lot of cases, is incredibly fragile and subject to many problems such as bit rot and errors, proprietary and complex formats and file types, and costly storage. In reality the world is creating digital content at a staggering pace, resulting in petabytes of possibly important or disposable content. How do we deal with this in our work or even in our personal collections of video or photos?

The Library of Congress has provided a thorough resource for individuals to get a handle on the digital content they are creating, as well as digitizing to share with family and friends across the globe. This is a rapidly increasing need of people everywhere, but how do we decide what do we keep and how much? Witness.org stands out as a good example of an organization that is also promoting a more curatorial culture for our content at large, and for a purpose. They provide a guide to archiving content from a journalism/activist perspective, from creation to preservation and access.

Working in a memory institution, I often feel like I’m helping usher content from the past into the future and that is a tremendously gratifying feeling. ‘This work will outlive us,’ is something I often hear said in libraries and archives and while that is true, there is a huge amount of effort and a lot of tough decisions that go into conservation, preservation, and access. Whether it’s a beautiful tome from the 17th century or video of one of the last known public appearances of Jimmy Hoffa, it takes detailed work, resources, and careful planning to keep these things alive. In reality, history is written by every one of us. What’s your story?

 

Parchment-making

by Michele Brown

Parchment is a tough, long-lasting writing and book covering material used historically for important documents and still used for the transcription of some religious and government laws. Consequently, Cornell’s copy of the 13th Amendment was written on parchment. My previous post described its conservation treatment.

Legend has it that parchment was developed in the kingdom of Pergamon during the second century BC  as a result of a shortage of papyrus. (1) Scholars disagree on the reason for the shortage of papyrus, but it is widely accepted that parchment production was first refined in Pergamon, which became parchment’s namesake. Parchment-making has remained largely unchanged since its early beginnings.

Sometimes the term “vellum” is used for parchment.  Vellum, to be precise, is parchment made from calfskin. The terms parchment and vellum are now often used interchangeably.

How does parchment differ from leather since they are both made from animal skins?

Most leather is made from animal skin that has been treated with tannin. This changes the collagen of the skin so that it will be more durable. Since tannins are acidic, leather is also an acidic material.

Leather is usually dyed during the tanning process.

Leather is usually dyed during the tanning process.

Some skins are tawed rather than tanned. Very early books bound in Europe were often bound with alum-tawed leather. We will discuss tawed leather in another post.

Parchment is made by soaking an animal skin (usually from a goat, sheep or calf) in lime and then stretching it on a frame, scraping it to remove excess tissue and allowing it to dry under tension. During this process, the collagen of the skin is rearranged, but not chemically altered. The result is a material that is very smooth and hard, and also very sensitive to changes in humidity. Since it has been soaked in a solution with a high pH, it is basic.

Pergamena has been making leather and parchment for generations and has offered parchment-making workshops. The following images are from one of their workshops.

These are skins of dyed goatskin parchment drying under tension. The screen allows airflow on both sides of the skins.

The skins for calfskin parchment were treated differently. Since they weren’t being dyed, they were allowed to dry and were re-hydrated before being stretched for scraping.

Once the skins were stretched and clipped, they were scraped to make them thinner. Parchment-makers use a curved knife called a lunellum for this purpose.

Parchment can be difficult to work with because it has a hard surface and, depending on its thickness, can be somewhat inflexible. It is extremely sensitive to changes in humidity and using adhesives can be problematic. However, it is a beautiful and resilient material and with good care will last for centuries.

 

(1)  In Natural History, Book XIII, Pliny ascribes the cause of the papyrus shortage to the rivalry between King Ptolemy V, who was building the library of Alexandria and King Eumenes II, who was building the library at Pergamon. Some sources say that King Ptolemy cut off the papyrus supply to Pergamon, forcing it to come up with an alternative source of writing material.

 

Re-housing the Thirteenth Amendment

by Michele Brown

The 13th Amendment, abolishing slavery and involuntary servitude was formally passed by Congress on January 31, 1865 and ratified by the states December 6, 1865.(1) Cornell University Library owns one of the 15 copies signed by Lincoln.  Cornell’s copy of the 13th Amendment is a “Congressional copy” and was donated to the University by the Nicholas H. Noyes family in the 1950s.

Like other important documents, the 13th Amendment is written on parchment. Parchment is a writing material made from animal skin that’s been dehaired, soaked in lime, scraped and stretched. We will have another post specifically about parchment production.  Some types of paper are also referred to as parchment, but it would be more accurate to describe them as “parchment-like.” See here for descriptions of parchment, vellum and parchment paper. Parchment has long been used for important documents because it is considered to be the most permanent and stable writing material.

2014 was an eventful year for Cornell’s copy of this important document. In April, it was removed from its 20th century frame and scanned using hyperspectral imaging.

This gave us an excuse to examine the matting and framing materials supporting our copy of the 13th Amendment. Cornell’s copy is housed in an elaborately carved wooden frame. A decorative headpiece with the words  “Proclaim Liberty throughout all the land, and unto all the inhabitants thereof” was attached to the document at some point. From the label on the back of the frame we assume the document was put into this frame in 1938 by Beard Art Galleries.

We were concerned that the document seemed to be unnaturally flat within the frame and we wondered how it had been attached to the backing board.

The document was taped to the backing board.

Now, we could see that the document was stuck directly to the backing board. This was a common method for controlling parchment, but it is not good for the document. Parchment needs to be able to respond to changes in humidity. If it is constrained too tightly while experiencing changes in humidity, it may split. Fortunately, it was easily lifted off the backing board, although first we had to remove the staples!

Staples had been used to hold the document to the backing board.

When the document was free of the backing board we could see that it wanted to curl. We could also see that the headpiece was cut from thinner parchment than the document itself.

The document started to curl once it was lifted off the backing board.

There was a residue of glued paper tape around the edges of the document and the headpiece. This residue was removed mechanically and by lightly rubbing with damp cotton.

In order to humidify and flatten the document, we decided to separate the two pieces.

The headpiece was separated from the document using a Teflon folder.

They were allowed to dry for several weeks and then were reattached using hot gelatin.

Now, we had to decide how to re-mat the document.

For the reasons stated above, we did not want to re-attach the document directly to the backing board. Instead, parchment documents are often attached to the backing board of a mat by using pieces of string that have been attached to the document and which are then wrapped around to the back. After careful consideration we decided to instead use strips of Japanese tissue.  This method was described by Nicholas Pickwoad in The Paper Conservator (2). The tissue strips were attached to the back of the document using stiff wheat starch paste and then attached to the back of the board. This will allow the document  to expand and contract as needed due to changes in the relative humidity. If the humidity becomes too low, the paper strips will break rather than the parchment itself splitting. We decided to use usumino (thick) tissue from Hiromi Paper for the strips.

We constructed a new backing board by laminating 3 layers of archival mat board cross-grained, with the short grain piece in the middle and using wheat starch paste as the adhesive.

Because the humidity in the conservation lab was relatively low, we moved the the document to the Kroch vault to attach the document to the backing board. The vault has a better humidity for parchment and it is where the document will spend most of its time. This allowed us to apply tension to the strips while the parchment was in a relaxed state.

Ariel Ecklund of Corners Gallery in Ithaca cut a new window mat from archival mat board and then reassembled the document with its new mat and its original decorative mat back into the frame. She replaced the 1930’s glass with museum glass. She added thickness to the original frame to provide better attachment for the framing points.
