Connection files contain all the information necessary for EndNote to search and import references from an on-line database. There are more than 2700 Connection Files available here for EndNote.You can download files individually below or as a complete set.
NOTE: rename any files you have customized as the new versions will overwrite existing files. Once the file(s) is downloaded to your desktop, copy the file(s) to the appropriate folder in your EndNote program directory (usually located in Windows—C:\Program Files\EndNote\Connections or Mac OS X— Harddrive: Applications: EndNote: Connections).

The Sorting and Filtering Options help you locate specific Connection Files by the date, information provider, database name or category (e.g. University). You can also download files individually via FTP: Mac / Windows. If you don't see a connection file you are looking for you can suggest a new connection file, as well as updates to an existing file.
