Creating an EndNote Library
Creating an EndNote library is similar to creating a file or document. Think of a name for your library and where you’d like to store it. EndNote will suggest a default library called My EndNote Library.
To create an EndNote library:
EndNote library filenames are automatically given the extension .enl (for EndNote Library). Each library has an .enl file and a .Data folder associated with it. Figures, groups, and other files are stored in the .Data folder, which is associated with each library and stored in the same folder as the main library file. It is important to always move, copy, rename, and delete both the main .enl file and the corresponding .Data folder for each EndNote library.
One Library or Several?
There is no limit to the number of EndNote libraries you can create, but it is usually best to create only one library for each general topic or field.
Creating Custom Groups
EndNote displays all of your references in All References, but it also allows you to create up to 500 groups of saved references. These are called Smart groups and Custom groups. A Custom group is built by specifically adding individual references to the group, whereas a Smart group is compiled automatically and is based upon a search strategy. Custom groups are a helpful way for everyone to organize their references into different categories or groups.
