Throughout the 1950s and 1960s, they increased Weiser Books' specialist focus on the occult at a time when many bookstores refused to handle such subjects.
After Crowley's death, most of his papers and other possessions were shipped to Germer, including the unbound sheets of the 1936 edition of his book The Equinox of the Gods.
[note 1] Germer also sold Weiser a collection of the First Edition of Crowley's masterwork on the tarot, The Book of Thoth.
The development of the 1960s "counter-culture," and the growth of popular interest in esotericism and Eastern religious and mystical traditions, allowed Ben and Donald Weiser to expand the company's publishing activities.
[4] The move gave Donald Weiser, who now ran the business with the assistance of Fred Mendel, the chance to further increase their specialisation.
The following year, they moved the company to its current premises in Cape Neddick, Maine: a one-time art gallery for American artist Walt Kuhn, which had more recently been the headquarters of Samuel Weiser Publishing.
For decades, the Weiser Bookstore issued printed catalogs that listed anywhere between a few hundred and several thousand items, with basic descriptions of the book's author, title, condition and price.
A large number have been devoted to the works of Aleister Crowley (in whom the store specialises), as well as authors including Dion Fortune, Israel Regardie, John Dee and Austin Osman Spare.
[6] The catalogs contain bibliographical, historical and biographical information about the books offered for sale, and often detail previously unpublished manuscript and other material.
