The Comstock Memorial Library of Entomology was established in 1914, when the students of John Henry Comstock created a book fund in his honor. Later, Professor Comstock increased the fund by personal contribution and donated his books to the library. The primary subjects of this library are general and applied entomology; related areas include parasitology, medical entomology, ecology, zoological nomenclature, and allied orders of arthropods. The library has an extensive number of reprints, a collection of departmental theses, and rare books.
