Zotero is an excellent program for managing data for bibliographies, footnotes, and reference lists. It is a plug-in for the Firefox web browser that allows users to either type in author, title, and other publication data manually or enter it automatically from library catalogs.
To install it, simply select "add-ons" from the Firefox tool menu. Click on "Get Add-ons" and type "Zotero" in the search box. When Zotero appears, click the "Add to Firefox" button. After restarting firefox "Zotero" will appear in the lower right of the browser window. Clicking on "Zotero" here will open the database for editing.
My college uses WorldCat to search library catalogs worldwide. Here is what I do to automatically enter information from WorldCat to Zotero: Use WorldCat as usual to find a book or other media you would like to save in Zotero. From the library catalog record window, click "Cite/Export." Then choose "Export to Endnote" in the resulting pop-up window. That's all it takes to automatically enter all the publication data into Zotero. When it is time to enter the information into a paper, Zotero lets you choose from several different citation styles and paste formatted entries right into your bibliography.
