First science fiction magazines
The first science fiction magazine, Amazing Stories, was published in a format known as bedsheet, roughly the size of Life but with a square spine. Later, most magazines changed to the pulp magazine format, roughly the size of comic books or National Geographic but again with a square spine. Now, most magazines are published in digest format, roughly the size of Reader's Digest, although a few are in the standard roughly 8.5" x 11" size, and often have stapled spines, rather than glued square spines. Science fiction magazines in this format often feature non-fiction media coverage in addition to the fiction. Knowledge of these formats is an asset when locating magazines in libraries and collections where magazines are usually shelved according to size.
