Online Library Catalogs

Conducting online research for your essay, term paper, or research paper? Here are links to online library catalogs from other parts of the world. These sites are a great source for your literature search, and many have links to other good news sources. I try to limit this list to those sites which are regularly updated, reliable, with a high percentage of "up" time.

Please contact me to report broken links, or to suggest other sources. Enjoy!
