PLOS (for Public Library of Science; PLoS until 2012) is a nonprofit publisher of open-access journals in science, technology, and medicine and other scientific literature, under an open-content license. It was founded in 2000 and launched its first journal, PLOS Biology, in October 2003.
As of 2024, PLOS publishes 14 academic journals, including 7 journals indexed within the Science Citation Index Expanded, and consequently 7 journals ranked with an impact factor.
PLOS Biology is a monthly peer-reviewed scientific journal covering all aspects of biology. Publication began on October 13, 2003. It is the first journal published by the Public Library of Science. The editor-in-chief is Nonia Pariente.
In addition to research articles, the journal publishes magazine content aimed to be accessible to a broad audience. Article types in this section are essays, "unsolved mysteries", editorials, and synopses.
Periodical literature (singularly called a periodical publication or simply a periodical) consists of published works that appear in new releases on a regular schedule (issues or numbers, often numerically divided into annual volumes). The most familiar example of periodical literature is the newspaper, but the magazine and the academic journal are also periodicals, as are some modern websites, e-journals, and other electronic-only publications produced recurrently on a schedule. Periodical publications cover a wide variety of topics, from academic, technical, and trade, to general-interest subjects such as leisure and entertainment.
Articles within a periodical are usually organized around a single main subject or theme and include a title, date of publication, author(s), and brief summary of the article. A periodical typically contains an editorial section that comments on subjects of interest to its readers. Other common features are reviews of recently published books and films, columns that express the authors' opinions about various topics, and advertisements.

The main focus of the open access movement has been on peer reviewed research literature, and more specifically on academic journals. This is because:
