Put simply, “open access” is the sharing of scholarly research at no cost to end users. Although it was first popularized in the Budapest, Bethesda, and Berlin statements in 2002 and 2003, there is still no universally agreed-upon definition for the term. At a minimum, a work must be freely available at no cost. Most proponents agree, additionally, that work must be released under a license that allows for it to be freely copied, used, and modified to qualify as open access. Although open access typically refers to scholarly journal articles, it can also be applied to monographs, gray literature, and other types of scholarly and nonscholarly work. Research is made available as open access in a number of ways. The two main models are “green” open access, where published works are placed in a free-to-access repository, and “gold” open access, where journals publish articles under a license that allows readers free access to their contents. In the nearly twenty years since the first open access declarations, its proponents have been broadly successful in propagating the movement’s ideals, with the result that more and more research in many subject areas has been made available under a green, gold, or other open access model. Many studies have shown that publishing a work as open access increases the number of citations it receives and improves its scores on a variety of metrics, although not all studies show a positive relationship. The growing support for open access, and upcoming initiatives like Plan S, in which a consortium of funders will require open access publishing as a condition of receiving funding, as well as continuing interest in open access from scholars, libraries, publishers, funders, and societies alike, means that open access is set to become ever more relevant to those studying scholarly communications, and research on the topic continues to grow accordingly. Research about open access is often practical in nature, and typically comes from scholars and researchers of scholarly communication, the publishing industry, or library and information science; however, because the benefits of open access apply to those in nearly all fields of study, researchers should be prepared to find studies and proponents that are interdisciplinary in nature or are published in journals outside of the sphere of communications.
