Library lexicographers will love this article from the Medium.com website. It offers a word list compiled by Jer Thorp who was inspired to ask Twitter if anyone had favourite obscure and/or delightful library or archival words. Mr. Thorp takes the best replies and provides a short glossary of library and archival terms.
By the way Mr. Thorp comes by his interest in library and archival terms honestly. He is currently the Innovator-in-Residence at the Library of Congress as well as a software artist, writer, and educator living in Brooklyn.
