Sente for Mac

From Third Street Software:

Sente 5 is the premier academic reference manager for Mac OS X. Sente's iTunes-like interface makes finding, reviewing, organizing and using the academic literature in your field easier than ever.

Sente (pronounced sen-tay) makes literature searches easier by providing a front-end to hundreds of data sources around the world, including: PubMed, many university library catalogs, Web of Science, Ovid, Agricola, the U.S. Library of Congress, and any other literature database that supports Z39.50 or SRU, and MARC or Dublin Core record syntax. (WoS and Ovid, and some other data sources, require a subscription.)

Sente updates the results of your searches each day so that you can easily stay current with new results. This means that you will learn about important new papers as soon as they appear in any of the databases you search. And the results will remain available until you find the time to review them, even if that happens when you are not connected to the Internet.

When it is time to write up your own research, Sente takes care of the details of properly formating citations and bibliographies. Sente includes over 100 pre-defined bibliography styles, including APA, Chicago and Harvard, as well as an easy-to-use bibliography format editor that lets you modify the supplied formats or create your own.
