Philosophy: Reference
Dictionaries, Encyclopaedias, and Search Engines

Specialist Philosophy Sites
*Dictionary of Philosophical Terms and Names
Maintained by Garth Kemerling. A steadily growing resource.
*Dictionary of Philosophy (1942)
Edited by Dagobert D. Runes; provided by Digital Text International.
*Dictionary of Philosophy of Mind
Edited by Chris Eliasmith. "This dictionary is intended as a free resource for all those interested in the philosophy of mind. The dictionary has a policy of blind peer review for all submissions to the dictionary."
*Encyclopedia of Science and Philosophy
Produced by the International Society for Complexity, Information, and Design. There's little philosophy here yet, in fact; the nearest I could find to a philosopher was Daniel Dennett (and that's not very close, let's face it).
*Erratic Impact: Philosophy Research Base
"categorized by history, subject and author. Integrating text resources with the best online resources, this study guide attempts to aid both academic and general interest in all philosophical genres and their related fields." I used to find this site useful, but not in its current version I'm afraid. For example, its choice of 50 Famous Philosophers is not only heavily slanted to the Continental, but is idiosyncratic at best (using both "famous" and "philosophers" rather non-standardly), and entries often do little more than puff a small number of books.
*Internet Encyclopedia of Philosophy
Maintained by Jim Fieser. Rapidly becoming one of the two major on-line philosophy encyclopædias; large and growing.
"Lexikon der Philosophie". German philosophical dictionary maintained by Uwe Wiedemann.
*Philosophy Lists
Maintained by Tony Cole. An attempt to provide information on western philosophy as practised around the world. It includes evaluative guides to journals, books, and departments.
*Powszechna Encyklopedia Filozofii | Universal Encyclopedia of Philosophy
Published by the Polish Thomas Aquinas Association. Four volumes have been published so far (up to "Iq", and articles from the first volume ("A–B") are provided on line.
*Routledge Encyclopedia of Philosophy Online Version 2.0
A pay site, with a couple of free sample articles.
*Stanford Encyclopedia of Philosophy
The other major on-line encyclopædia of philosophy. Big and getting bigger. Entries are up-dated when appropriate, and the number of entries is growing.
*The Window
"the comprehensive clearinghouse for philosophy on the Web". Maintained and written by Chris Marvin and Frank Sikernitsky.
General or Philosophically Relevant Sites
*Catholic Encyclopedia
A 1907 encyclopædia; most of it is philosophically irrelevant, of course, but where it is relevant it can be useful.
*Jewish Encyclopedia
Originally published between 1901 and 1906, like the Catholic Encyclopedia, the philosophically relevant entries can be very useful.
*MacTutor History of Mathematics Archive
Created and maintained by John J. O'Connor and Edmund F. Robertson at the University of St Andrews.
*Oxford Reference Online
For subscribers only (including members of subscribing institutions); very useful if you're entitled to access it.
*Thoemmes Encyclopedia of the History of IdeasPoorly written
"Our website has many other free and ever growing resources for scholars : A portrait gallery with over 400 portraits, The Encyclopedia has almost a 100 entries and is added to monthly, There are many bibliographies, title pages and extensive introductions to many of our titles." You'll only be able to access the other stuff easily if you're using the right browser, as the site depends upon a Usemap menu.
"a free-content encyclopedia that anyone can edit." Eavesdropping on the public discussions concerning proposed new entries, entries for deletion, etc., it's difficult to believe that this encyclopædia manages to be as useful as it (often but by no means always) is.
