An academic journal or scholarly journal is a periodical publication in which scholarship relating to a particular academic discipline is published. They serve as permanent and transparent forums for the presentation, scrutiny, and discussion of research. They nearly universally require peer review for research articles or other scrutiny from contemporaries competent and established in their respective fields.
Digitization is the process of converting information into a digital format. The result is the representation of an object, image, sound, document, or signal obtained by generating a series of numbers that describe a discrete set of points or samples. The result is called digital representation or, more specifically, a digital image, for the object, and digital form, for the signal. In modern practice, the digitized data is in the form of binary numbers, which facilitates processing by digital computers and other operations, but digitizing simply means "the conversion of analog source material into a numerical format"; the decimal or any other number system can be used instead.

Additionally, Google has partnered with a number of magazine publishers to digitize their archives.
The California Digital Library (CDL) was founded by the University of California in 1997. Under the leadership of then UC President Richard C. Atkinson, the CDL's original mission was to forge a better system for scholarly information management and improved support for teaching and research. In collaboration with the ten University of California Libraries and other partners, CDL assembled one of the world's largest digital research libraries. CDL facilitates the licensing of online materials and develops shared services used throughout the UC system. Building on the foundations of the Melvyl Catalog, CDL has developed one of the largest online library catalogs in the country and works in partnership with the UC campuses to bring the treasures of California's libraries, museums, and cultural heritage organizations to the world. CDL continues to explore how services such as digital curation, scholarly publishing, archiving and preservation support research throughout the information lifecycle.
A bibliographic database is a database of bibliographic records. This is an organised online collection of references to published written works like journal and newspaper articles, conference proceedings, reports, government and legal publications, patents and books. In contrast to library catalogue entries, a majority of the records in bibliographic databases describe articles and conference papers rather than complete monographs, and they generally contain very rich subject descriptions in the form of keywords, subject classification terms, or abstracts.
A digital library 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. In addition to storing content, digital libraries provide means for organizing, searching, and retrieving the content contained in the collection. Digital libraries can vary immensely in size and scope, and can be maintained by individuals or organizations. The digital content may be stored locally, or accessed remotely via computer networks. These information retrieval systems are able to exchange information with each other through interoperability and sustainability.

Sci-Hub is a shadow library website that provides free access to millions of research papers, regardless of copyright, by bypassing publishers' paywalls in various ways. Unlike Library Genesis, 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. The site is extensively used worldwide. In September 2019, the site's operator(s) said that it served approximately 400,000 requests per day. In addition to its intensive use, Sci-Hub stands out among other shadow libraries because of its easy use/reliability and because of the enormous size of its collection; a 2018 study estimated that Sci-Hub provided access to 95% of all scholarly publications with issued DOI numbers. On 15 July 2022, Sci-Hub reported that its collection comprised 88,343,822 files. Since December 2020, the site has paused uploads due to legal troubles.
Semantic Scholar is a research tool for scientific literature powered by artificial intelligence. It is developed at the Allen Institute for AI and was publicly released in November 2015.
