EndNote is a citation management program that helps you create, collect, and manage references in what it calls a "library" -- your collection of citations. Although you may enter records manually, nearly all producers of databases support a direct export to EndNote feature which allows you to import directly into EndNote multiple citations from the results of your search simultaneously.
EndNote allows you to attach files (PDFs, JPEGs, Word docs, MPGs, Excel...) to individual bibliographic records. In that way you have your source immediately at hand with its full citation.
Some 5,000 styles are available for citing entries, from the standards (APA, MLA, Chicago) to those required by individal journals (Cell Biology).
Cite-While-You-Write feature integrates EndNote with Word. Using it, you can begin writing and when you wish to cite a source, choose a reference from EndNote. The reference will appear in the style you have chose in the text and in the bibliography.
EndNote is available free to the students, faculty, and staff of Indiana University - Bloomington through our site license with Clarivate Analytics

The latest version of EndNote, EndNote X9.3.1, differs from earlier versions in that it is not backwards compatible. A library created using EndNote X9.3.1 or a library converted to EndNote X9.3.1 cannot be used by an earlier version. They explain:
EndNote X9.3: Library Conversion and Backward Compatibility
On a PC, if you still have Endnote X9.2 (or even X8) installed, you can continue to use it, although there will be no updates.
There are potential problems. If you want to send a library (a compressed library) that used Endnote X9.3.1 to someone who has Endnote X9.2, they will be unable to use it. (They suggest synchronize with the online EndNote as a way to share.)
If it doesn't matter, Endnote X9.3.1 converted libraries should work for you without trouble.
