PubMed has a feature, MyNCBI, that allows you to store both collections of articles and a bibliography. This is helpful when building a body of research and tracking information by different topics. You may create as many collections as you would like but only one bibliography is available.
To set up an account:
1. Go to PubMed.
2. In the upper right corner click on My NCBI Sign In.
3. Register for an account. On your personal computer, you can choose to stay signed in by checking the box next to "Keep me signed in unless I sign out." Then you will not have to sign in each time you go to PubMed.
