"Thrilling Love" was a pulp fiction title containing romantic stories by "popular authors." The Pulp Fiction collection at the Library of Congress consists of issues received on copyright deposit at the time of their publication. The "pulps," so called because they were printed on cheap high-acid-content paper, served as popular reading material, similar to today's paperback; cheap, portable, disposable and often sensational. This genre flourished from the 1920s to the 1950s. Titles focused on specific literary types: romance, sports, western, detective, science fiction, horror or military (during World War II). Writers were frequently paid by the word, and to meet daily living expenses, well-known authors sometimes wrote for these magazines under pseudonyms, putting only their "literary" work under their real name. Authors who got their start by writing for pulp fiction magazines include Raymond Chandler, Cornell Woolrich, Dashiell Hammett, H.P. Lovecraft, Isaac Asimov, Robert Heinlein and L. Ron Hubbard.
