Bradley-Garretson Company Limited Subscription publishing is a method of bookselling in which publishers, authors, and book agents used advertisements, sample books, and other promotional materials, to solicit subscribers in advance of publication, to avoid financial loss. A well-known example is Canadian Wild Flowers (Montreal, 1868), for which Agnes Fitzgibbon enlisted 400 subscribers. From c. 1870 to 1910, companies used various persuasive techniques to enlist book agents, and subscription publishing flourished in Canada. Bradley-Garretson, of Brantford and Toronto, Ontario, was one such publisher, and purported to have “two to three thousand” agents working across Canada in the mid-1880s.
