==General Handling Tips for 19th-Century Cloth-Case Bindings==
 
Nearly 40% of the 19th-century, cloth-case bindings analyzed for this project to date contain lead in the bookcloth. Analysis of a range of bookcloth colors has also identified arsenic, barium, chromium, copper, iron, and mercury.
 
No matter which pigments or dyes may be present, it is best practice to avoid ingesting anything or touching the face while handling 19th-century, cloth-bound books. It is also best practice to wash hands after handling books, especially before eating, drinking, or smoking.
 
 
 
==Emerald Green Bookcloth==
 
In early 2019, analysis of 19th-century, cloth-case publishers’ bindings at Winterthur Library revealed bookcloth colored with “emerald green,” or [https://cameochemicals.noaa.gov/chemical/2981 copper acetoarsenite], an inorganic pigment known to be extremely toxic. This pigment’s popularity in England and the United States during the Victorian era is well documented. While the colorant was known to be widely used in textiles for home decoration and apparel, wallpaper, and toys, its use specifically in bookcloth had not been formally explored. Successful commercial bookcloths were a closely guarded trade secret during the nineteenth century, limiting our current understanding of their materiality and manufacture.
 
 
 
Conservation staff and interns at Winterthur Museum, Garden and Library conducted an initial  survey of bookcloth pigments in the library’s circulating and rare book collections, further expanding their data set in cooperation with The Library Company of Philadelphia. Books published between 1837 and 1900, a time-period which aligns with the rising use of bookcloth on publishers' case bindings, were analyzed with X-ray fluorescence (XRF) spectroscopy. When arsenic and copper were detected together, Raman spectroscopy was used to confirm copper acetoarsenite.
 
 
 
The first 200 books tested represented a range of vivid bookcloth colors. Thereafter, only books covered in green cloth were selected for analysis, in order to focus on arsenic and move through the collection more efficiently. Now that analysis of green bindings is complete, other colors of bookcloth continue to be analyzed in stages.
 
 
 
Nearly 350 green cloth bindings in the collections of Winterthur and The Library Company of Philadelphia were analyzed. Two books procured from second-hand booksellers were also included in the testing, and were confirmed to contain emerald green. In total, 39 green cloth bindings were found to contain arsenic. Quantitative analysis performed at the University of Delaware Soil Testing Lab indicated that emerald green bookcloth colorant is extremely friable and offsets a significantly detectable amount of arsenic. Emerald green publishers’ bindings present a health risk to librarians, booksellers, collectors, and researchers, and should be identified, handled, and stored with caution.
 
 
 
==Trends in Use of Emerald Green Bookcloth==
 
Based on the data collected at Winterthur Library and The Library Company of Philadelphia, the following trends in the use of emerald green bookcloth have been identified:

* Vibrant green bookcloth covering the boards (front and back covers)
 
* Vibrant green or faded brownish bookcloth on the spine
 
* Gold and blind stamped decoration, often paired with gilt textblock edges
 
* English or American imprint
 
* Publication date primarily between 1840s-1860s
 
* Variations on a morocco grain pattern are common, although other bookcloth grains have also been identified
 
 
 
We have developed a <b>color swatch bookmark</b> to aid in the visual identification of volumes potentially bound in emerald green bookcloth.
 
 
 
==Emerald Green Color Swatch Bookmark==
 
As of July 2021, we have mailed over 580 bookmarks to 34 of the United States and 17 countries around the world. These bookmarks are intended to assist with visual identification of bookcloth which ''may'' be pigmented with copper acetoarsenite (emerald green). To receive a color swatch bookmark, please email [mailto:reference@winterthur.org?Subject=URL%20Encoded%20Subject&body=Body%20Text reference@winterthur.org] and write “Emerald Green Bookmark” in the subject line. Please include the following information in your email:

==Safe Handling & Storage Tips for Arsenical Books==
 
 
 
Avoid opportunities for ingestion or inhalation of emerald green pigment. Avoid eating, drinking, smoking, biting fingernails, or touching the face while handling potentially arsenical bookcloth.
 
 
 
<B>Wear nitrile gloves:</B>
 
 
 
Avoid handling suspected emerald green bookcloth with bare hands. Although arsenic is unlikely to be absorbed through the skin, it can offset onto the hands and be ingested or inhaled through touching the face or eating/drinking. Handling books with damp or sweaty hands can increase the risk of arsenic offsetting onto the skin.
 
 
 
<B>Wash hands:</B>
 
 
 
Even when using gloves, wash hands after handling suspected emerald green bookcloth.
 
 
 
<B>Isolate book for storage:</B>
 
 
 
If a book is suspected to be bound in emerald green bookcloth, seal the book in a zip-top, polyethylene baggie to limit handling and contain potentially friable pigment. Winterthur Library relocated arsenical books from its circulating collection to its rare book collection.
 
 
 
<B>Wipe down surfaces:</B>
 
 
 
Handle books bound in emerald green bookcloth on hard surfaces (such as a table), and avoid upholstered surfaces (such as an armchair). After handling, wipe down hard surfaces that have come into contact with the book using a damp, disposable cloth.
 
 
 
<B>For Conservators:</B>
 
 
 
A professional conservator performing a conservation treatment on a book bound in emerald green bookcloth should observe the same precautions as above. In addition, work under a certified chemical fume hood. If a chemical fume hood is not available, a second option is to conduct treatment using a ductless fume hood for particulates with a combination HEPA/charcoal filter. Be aware that the introduction of wet adhesives could cause arsenic to migrate in greater concentration toward the source of moisture.
 
 
 
==Disaster Planning & Response for Arsenical Books==
 
 
 
Should a disaster situation arise involving fire or water, the risks associated with arsenical bookcloth increase. These risks can be mitigated with disaster planning and labeling. Consider storing arsenical books together in one storage area which can be clearly labeled for disaster responders, in addition to item-level caution labels on individual enclosures. While proper PPE should always be worn during salvage, make sure the need for PPE when handling arsenical books is emphasized in written disaster plans.
 
 
 
==Arsenical Books List==
 
 
 
In the nineteenth century, not every book from the same edition would have been bound identically. Therefore, it is possible to have a book of the same edition listed below, but which is not bound in emerald green bookcloth. We provide this list of books bound in emerald green bookcloth as a starting point from which other institutions and private collectors may consider their own collections. This table includes information collected from bookmark recipients about possible emerald green bindings, as well as more conclusive identification by Winterthur and other institutions with access to XRF, Raman, and PLM. Visual identification of emerald green using a color swatch bookmark is understandably less reliable than instrumental analysis, so we have included the identification method(s) used for each book. This table was last updated on July 30, 2021. Updates about how to submit data to the project will be posted here in fall 2021.

==Methodology & Results of Analysis==
 
 
 
English-language books published between 1837 and 1900, a time-period which aligns with the rising use of bookcloth on publishers' case bindings, were identified at Winterthur Library through the WinterCat OPAC. The first 200 books tested represented a range of vivid bookcloth colors. Thereafter, only books covered in green cloth were selected for analysis, in order to focus on arsenic and move through the collection more efficiently.  X-ray fluorescence (XRF) was used to collect elemental information from bookcloths. When arsenic and copper were found together, Raman spectroscopy was used to confirm copper acetoarsenite. A total of 406 books from the Winterthur collection were analyzed, and ten were confirmed to contain copper acetoarsenite. An additional two books procured from second-hand booksellers tested positive for arsenic and copper.
 
 
 
The Library Company of Philadelphia shelves its Americana collection chronologically according to publication date. Volumes were selected for testing by visual scan of the shelves in the appropriate date range (1830s through 1900). Approximately 80 books bound in green bookcloth or with green paper onlays were tested using handheld XRF. Spectra and bibliographical data were saved for each volume which showed the presence of arsenic and copper. A total of 28 books from the Library Company collection were found to contain arsenic.
 
 
 
The University of Delaware Soil Testing Lab performed quantitative analysis on a destructive sample from one Winterthur Library volume and measured significant levels of arsenic. Quantitative analysis for arsenic on a dry cotton swab rolled across the surface of the bookcloth indicated that the bookcloth colorant is extremely friable and offsets a significantly detectable amount of arsenic.
 
 
 
In an effort to explore additional techniques for the reliable identification of emerald green, bookcloth colorants were analyzed by polarized light microscopy. Samples were removed from seven books that had been previously analyzed by XRF and Raman spectroscopy. The books were selected and sampled by researchers other than the microscopist in order to emulate the analysis of unknown pigments. Examination in plane- and cross-polarized light conclusively and correctly identified emerald green as the colorant in three of the samples, and found a mixture of Prussian blue and chrome yellow in the other four. While all optical characteristics observed in the samples were considered in the interpretation of the results, the presence of spherulites was the most distinctive diagnostic in the identification of emerald green. Tips and recommendations for sampling, sample preparation, and analysis by PLM were compiled into a document available upon request from mtedone[at]winterthur[dot]org or rgrayburn[at]winterthur[dot]org.
