Good news for SBTS students: I was just informed that SBTS students now have access to the religion, history, and philosophy Oxford Handbooks online. If you are on campus, you can navigate directly to oxfordhandbooks.com, and explore to your heart's content. Off campus access is on the way. When it is ready, off-campus students will access the site via the SBTS library databases page. (Update: off-campus access is ready to roll.)
These should be the most used resources the library owns. No matter what paper you are writing, you should find help in the Oxford Handbooks. There are 66 handbooks listed in the religion category, 73 in philosophy, and 40 in history. Each handbook contains in-depth surveys and fantastic bibliographies.
