Gathering References

Refworks, a subscription web-based citation manager, is a great way to manage bibliographies. Most databases export directly to Refworks, and for those that don't, Refworks can accept imported .txt files. There are various output styles for citations, including MLA, APA and Chicago.

ottobib is a free web widget that converts ISBNs into citations. You can type a list of ISBNs separated by commas and get a bibliography in MLA, APA or Chicago styles.
