История JSTOR: от цифровой библиотеки к анализу данных.

Distributor of ebooks and other digital media

William G. Bowen, president of Princeton University from 1972 to 1988, founded JSTOR in 1994. JSTOR was originally conceived as a solution to one of the problems faced by libraries, especially research and university libraries, due to the increasing number of academic journals in existence. Most libraries found it prohibitively expensive in terms of cost and space to maintain a comprehensive collection of journals. By digitizing many journal titles, JSTOR allowed libraries to outsource the storage of journals with the confidence that they would remain available long term. Online access and full text searchability improved access dramatically. Bowen initially considered using CD ROMs for distribution. However, Ira Fuchs, Princeton University's vice president for Computing and Information Technology, convinced Bowen that CD ROM was becoming an increasingly outdated technology and that network distribution could eliminate redundancy and increase accessibility. (For example, all Princeton's administrative and academic buildings were networked by 1989; the student dormitory network was completed in 1994; and campus networks like the one at Princeton were, in turn, linked to larger networks such as BITNET and the Internet.) JSTOR was initiated in 1995 at seven different library sites, and originally encompassed ten economics and history journals. JSTOR access improved based on feedback from its initial sites, and it became a fully searchable index accessible from any ordinary web browser. Special software was put in place to make pictures and graphs clear and readable. The Andrew W. Mellon Foundation funded JSTOR initially. Until January 2009, JSTOR operated as an independent, self sustaining nonprofit organization with offices in New York City and in Ann Arbor, Michigan. Then JSTOR merged with the nonprofit Ithaka Harbors, Inc.—a nonprofit organization founded in 2003 and "dedicated to helping the academic community take full advantage of rapidly advancing information and networking technologies".

JSTOR content is provided by more than 900 publishers. In addition to the main site, the JSTOR labs group operates an open service that allows access to the contents of the archives for the purposes of corpus analysis at its Data for Research service. This site offers a search facility with graphical indication of the article coverage and loose integration into the main JSTOR site. Users may create focused sets of articles and then request a dataset containing word and gram frequencies and basic metadata. They are notified when the dataset is ready and may download it in either XML or CSV formats. The service does not offer full text, although academics may request that from JSTOR, subject to a non disclosure agreement. JSTOR Plant Science is available in addition to the main site. JSTOR Plant Science provides access to content such as plant type specimens, taxonomic structures, scientific literature, and related materials and aimed at those researching, teaching, or studying botany, biology, ecology, environmental, and conservation studies. The materials on JSTOR Plant Science are contributed through the Global Plants Initiative (GPI) and are accessible only to JSTOR and GPI members. Two partner networks are contributing to this: the African Plants Initiative, which focuses on plants from Africa, and the Latin American Plants Initiative, which contributes plants from Latin America. JSTOR launched its Books at JSTOR program in November 2012, adding 15,000 current and backlist books to its site. The books are linked with reviews and from citations in journal articles. In September 2014, JSTOR launched JSTOR Daily, an online magazine meant to bring academic research to a broader audience. Posted articles are generally based on JSTOR entries, and some entries provide the backstory to current events. Reveal Digital is a JSTOR hosted collection of documents produced by or about underground, marginalized and dissenting 20th century communities. Reveal Digital's open access content includes zines, prison newspapers, AIDS art, student movement documents, black civil rights materials, and a white supremacy archive. Individual subscriptions also are available to certain journal titles through the journal publisher. Every year, JSTOR blocks 150 million attempts by non subscribers to read articles. Inquiries have been made about the possibility of making JSTOR open access. According to Harvard Law professor, JSTOR had been asked "how much would it cost to make this available to the whole world, how much would we need to pay. ".

In late 2010 and early 2011, Aaron Swartz, an American computer programmer, writer, political organizer and Internet activist, used MIT's data network to bulk download a substantial portion of JSTOR's collection of academic journal articles.

The availability of most journals on JSTOR is controlled by a "moving wall", which is an agreed upon delay between the current volume of the journal and the latest volume available on JSTOR. This time period is specified by agreement between JSTOR and the publisher of the journal, which usually is three to five years. Publishers may request that the period of a "moving wall" be changed or request discontinuation of coverage. Formerly, publishers also could request that the "moving wall" be changed to a "fixed wall"—a specified date after which JSTOR would not add new volumes to its database. , "fixed wall" agreements were still in effect with three publishers of 29 journals made available online through sites controlled by the publishers.

Beginning September 6, 2011, JSTOR made public domain content available at no charge to the public. In January 2012, JSTOR started a pilot program, "Register & Read", offering limited no cost access (not open access) to archived articles for individuals who register for the service. At the conclusion of the pilot, in January 2013, JSTOR expanded Register & Read from an initial 76 publishers to include about 1,200 journals from over 700 publishers. Registered readers may read up to six articles online every calendar month, but may not print or download PDFs. In 2013, more than 8,000 institutions in more than 160 countries had access to JSTOR. As of 2014, JSTOR is conducting a pilot program with Wikipedia, whereby established editors are given reading privileges through the Wikipedia Library, as with a university library.

In 2012, JSTOR users performed nearly 152 million searches, with more than 113 million article views and 73.5 million article downloads. JSTOR metadata is available through CrossRef and the Unpaywall dump, which as of 2020 identifies nearly 3 million works hosted by JSTOR as toll access, as opposed to over 200,000 available in open access (mainly through third party open access repositories).
