Started in 1743 by no less of an Enlightenment personage than Benjamin Franklin, the American Philosophical Society (APS) has played an important role in American cultural and intellectual life for over 250 years. The APS "promotes useful knowledge in the sciences and humanities through excellence in scholarly research, professional meetings, publications, library resources, and community outreach." From the APS mainpage, visitors can learn about doing research at the APS's very fine library, read about fellowship and grant opportunities, and search a database of its current members. In the section dedicated to providing information on the annual meeting, visitors can view programs from past gatherings, and view the 2003 proceedings online. If individuals can't make it to Philadelphia to visit the APS exhibits, they may look at archived online exhibits here, which include an overview of the many fine holdings -- including first editions of Isaac Newton's Principia and Charles Darwin's _Origin of Species_. The site is rounded out by information on visiting the APS and its various publication series.
