# 3. Adding references to a library

When you create a new library, it is initially empty. You will have to fill it with references yourself. How to do this is explained in this part of the training.

There are three methods for doing this.

1. Importing references from a database
2. Manually adding a reference
3. Search and import references via EndNote (see section 6.1, advanced options).

After adding a reference, you can always edit it at a later date. For how to do this, see section 4.4.
