Core Journals in Library and Information ServicesIn the library science field, there is no professionally accepted tiered list of journals in the United States to guide librarians, as there is in other academic disciplines. This situation creates a challenge for both new and experienced librarians who wish to make a serious contribution to librarianship by publishing articles. This article outlines a methodology used at the Libraries of Purdue University, which could be adapted by other university libraries, to create a tiered list of journals tailored to the institution. The article begins with a literature review that identifies a short list of top-level journals. This is followed by the methodology that uses expert opinion surveys, acceptance and circulation rates, impact factors, h-indexes, and journals with local faculty articles. Tables with the journals ranked into three tiers are included.
