JSTOR ('dʒeɪstɔːr; short for Journal Storage) is a digital library founded in 1994. Originally containing digitized back issues of academic journals, it now encompasses books and other primary sources as well as current issues of journals in the humanities and social sciences. It provides full-text searches of almost 2,000 journals. Most access is by subscription but some of the site is public domain, and open access content is available free of charge.
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vice president for Computing and Information Technology, convinced Bowen that CD-ROM was becoming an increasingly outdated technology and that network distribution could eliminate redundancy and increase accessibility.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.

Sci-Hub is a shadow library website that provides free access to millions of research papers, without regard to copyright, by bypassing publishers' paywalls in various ways. It does not provide access to books. Sci-Hub was founded in Kazakhstan by Alexandra Elbakyan in 2011, in response to the high cost of research papers behind paywalls (see Serials crisis). The site is extensively used worldwide. In September 2019, the site's operator(s) said that it served approximately 400,000 requests per day.
New York, often called New York City or NYC, is the most populous city in the United States. With a 2020 population of 8,804,190 distributed over , New York City is the most densely populated major city in the United States. The city is more than twice as populous as Los Angeles, the nation's second-largest city. New York City is situated at the southern tip of New York State. Situated on one of the world's largest natural harbors, New York City comprises five boroughs, each of which is coextensive with a respective county.
A digital library, also called an online library, an internet library, a digital repository, a library without walls, or a digital collection is an online database of digital objects that can include text, still images, audio, video, digital documents, or other digital media formats or a library accessible through the internet. Objects can consist of digitized content like print or photographs, as well as originally produced digital content like word processor files or social media posts.
