Hi Mark and all, If the topic of arsenic-containing Victorian-era bookbindings interests you, please visit the Poison Book Project Wiki: http://wiki.winterthur.org/wiki/Poison_Book_Project, where you will find our bibliography on the topic, including several recordings of Zoom presentations and a link to our 2022 JAIC article, among other resources; as well as handling and storage recommendations. The wiki also includes a crowdsourced list of known arsenical, 19th-century bookbindings, which is now at 128 volumes. If you find any such volumes in your own collections (private or institutional), I hope you will let us know. There are guidelines on the wiki for how to contribute data to the project. Best wishes for the safe enjoyment of historical books, Melissa ... Dr. Melissa A.
