The Online Search command on EndNote’s Tools menu connects you to online databases and library catalogs so that you can search them from within the EndNote program and retrieve references directly into EndNote. EndNote is able to make these connections using the information stored in the hundreds of individual "connection files."
This section describes how to edit and create connection files. The process of using the Online Search command is described in Quick Overview (Online Searching).
EndNote provides thousands of connection files for a variety of sources. By default, only the most popular connection files are stored in the Connections folder in your EndNote folder. You can view all available connection files by selecting Connection Files from the Edit menu, and then selecting Open Connection Manager.
To install additional connection files, see Installing Additional Connection Files.
A connection file contains all the information necessary to connect to, search, and import references from an online database or online library catalog. Each connection file represents a different online database (such as the Library of Congress or PubMed from the National Library of Medicine).
