Abstract: Book acquisition is the basic work in library literature resource construction. By introducing the Information Foraging Theory into book acquisition, this paper tried to provide better guidance for acquisition librarians to get effective access to publication information resource. It indicated that acquisition librarians should foster the consciousness of information clues through designating information sections and building core authors and core press database, and strengthen information foraging skills and create co-construction and sharing mechanism, so as to improve the overall acquisition ability based on collaborative information foraging.
