The E. K. Harry Library of Fishes, located on the second floor of the IGFA Fishing Hall of Fame & Museum, is the information center of the International Game Fish Association. Its mission is to collect, document, and preserve significant materials and artifacts relating to the past, present and future of sport fish and sport fishing, to provide access to these materials, and to disseminate information to the local, national and international public.

Though the International Game Fish Association had been collecting materials since its inception in 1939, the Library was officially established in 1973 by IGFA President Elwood K. Harry in response to the recognized need for a permanent repository for angling literature, films, photographs and artifacts. Today it enjoys a reputation as the most extensive and comprehensive recreational fishing collection in the world.

The E. K. Harry Library of Fishes currently contains more than 15,000 books, from first editions of angling classics to the latest books in print; 150 outdoor and fishing magazines from many countries and in many languages (some of which go back to the 1930s); 2,100 videos, including classic fishing films from the 1930s, 1940s and 1950s as well as modern releases; hundreds of technical journals, papers and bulletins from scientific institutions, government agencies and individual researchers; an extensive collection of newsletters and yearbooks from organizations and fishing clubs; thousands of slides and photographs ranging from historic record catches and exciting action shots of fish and fishing to famous anglers of yesterday and today; memorabilia from sport fishing greats, including documents, research, news clippings, scrapbooks, and private correspondence; fish mounts; original art; trophies; a stamp collection; and much more. Title, author and subject access (by more than 5,000 fishing-related subject headings) to the entire collection is provided by the Library's unique database.
