In 2012, I began a custom of sharing the essays contained in Contributions to Biblionotes with my friends and readers each Christmas. Walter Harris wrote these essays for the Bibliomites in the 1950s. And when he died in 1982, he was described in the Antiquarian Book Monthly Review as "one of the three most knowledgeable bookmen who ever lived."
"Ex-Libris" was the first essay I shared, followed by "Chapbooks" in 2013. And to provide more background information for you, I posted "About Bibliomites, Biblionotes and Walter 'Wally" Harris" on my Biblio-Researching blog in December 2013.
