Data entry is a largely menu-driven three-step procedure.
Step 1: choose existing or enter new reference:
Option 1: Select from existing reference. You may type any part of an author's last name to narrow down selection.
Option 2: Enter new reference. You may copy and paste PubMed ID and then click "Get Information" to retrive information from PubMed and automatically fill the fields. Use "check existence" to confirm the PubMed ID in PubMed website. You can manually type the information.
