The Internet Encyclopedia of Philosophy (IEP) is a scholarly online encyclopedia, dealing with philosophy, philosophers, and related topics.[1] The IEP publishes only peer-reviewed and blind-refereed original papers. Contribution is generally by invitation, and contributors are recognized as leading international specialists within their field.[1][2]


The IEP was founded by philosopher James Fieser in 1995, operating through a non-profit organization with the aim of providing accessible and scholarly information on philosophy.[3] The current general editors are philosophers James Fieser and Bradley Dowden (since 1999) with a staff of thirty faculty members as subject-area editors plus numerous volunteers.[4][2] The entire website was redesigned in 2009, moving from static HTML pages[citation needed] to the open-source content management system WordPress.[5] In 2024, it contained 880 articles.


The general editors supervise thirty subject-area editors, who help recruit authors and referees. The area editors supervise the blind-refereeing process. The intended audience for the IEP is philosophy students and faculty who are not specialists within the field, and thus articles are written in an accessible style. Articles consist of a brief survey or overview, followed by the body of the article, and an annotated bibliography. Articles are searchable either by an alphabetical index or through a Google-power search mechanism.[2]


During any twelve month period it receives 6.9 million viewers, making it the most visited encyclopedia of professionally written philosophy articles. Similarweb analytics[6] and Google Analytics say 75% of this usage is through internet searches, 18% is through direct access, and 5% through referral, with the referring websites including other reference websites and university library guides.[6]


The IEP is included by the American Library Association in its listing of Best Free Reference Sites;[7] listed as an online philosophy resource by the Federation of Australasian Philosophy in Schools Associations;[8] listed by EpistemeLinks as one of the "outstanding resources" in philosophy on the internet;[9] and listed as a reliable resource in many university philosophy guides.[10]
