REP Online is the online version of the Routledge Encyclopedia of Philosophy. Published in June 1998 in print and CD-ROM editions, this was the first multi-volume Encyclopedia released in the discipline for over thirty years. It was immediately received as a monumental, ground-breaking work and won numerous awards including Editor's Choice (Reference Books Bulletin), 50 Sources for the Millennium (Library Journal) and Outstanding Reference Source (American Library Association).

REP Online will be an invaluable addition to your collection. It is the most up-to-date philosophy resource available. Teachers, lecturers and students can access the resource as a personal teaching or learning tool at the same time - it can cross complex academic campus or public library networks.

  • - 25,000 hot-linked cross-references between articles;
  • - a comprehensive conceptual organisation of key terms, themes and names;
  • - and articles organised by theme, philosophical traditions by region, religious traditions, and period.
