These publications, typically disseminated through postal services, present a curated selection of reading material available for purchase. Customers peruse the offerings, submit their orders via mail, and receive the selected books delivered directly to their residences. A historical example is the Sears Roebuck catalog, which, in addition to various goods, offered books to a widespread audience.
Such resources played a significant role in expanding access to literature, particularly in areas with limited bookstore availability. They afforded individuals the opportunity to discover new authors and genres from the comfort of their homes. These facilitated literacy and knowledge dissemination before the widespread adoption of digital marketplaces, and they satisfied consumer demands for reading materials.
