The Internet Encyclopedia of Philosophy (IEP) is a scholarly online encyclopedia, dealing with philosophy, philosophical topics, and philosophers. [1] The IEP combines open access publication with peer reviewed publication of original papers. Contribution is generally by invitation, and contributors are recognized and leading international specialists within their field. [2] [3]



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. [4] The current general editors are philosophers James Fieser and Bradley Dowden, with the staff also including numerous area editors as well as volunteers. [5] [6] The entire website was redesigned in the summer of 2009, moving from static HTML pages to the open-source publishing platform WordPress . [7]


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. [8] Articles consist of a brief survey or overview, followed by the body of the article, and an annotated bibliography. [9] Articles are searchable either by an alphabetical index or through a Google-power search mechanism. [9]


Similarweb analytics suggest that the IEP website is accessed worldwide between two and three million times per month. [10] Some 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. [10]


The IEP is included by the American Library Association in its listing of Best Free Reference Sites; [11] listed as an online philosophy resource by the Federation of Australasian Philosophy in Schools Associations; [12] listed by EpistemeLinks as one of the "outstanding resources" in philosophy on the internet; [13] and listed as a reliable resource in many university philosophy guides.
