Note: When you begin writing, you may find that you need to do additional research. This is normal.
If You Have a Known Source as Your Starting Point
READ the document.
Highlight cited resources within the document that are relevant to the issue which you have been asked to research.
READ these resources.
If you have an annotated document, such as an annotated statute or regulation, read the annotations and pull out relevant materials & citations.
Shepardize/KeyCite the document – primary sources have citing references; some secondary sources do as well.
Other Tips
Law firms and other legal offices often have their own work product banks, so you can see previous examples of forms, briefs, etc., produced by the organization’s own attorneys.
If you’re faced with a topic about which you know nothing, start by looking at research guides rather than jumping straight into a paid database such as Westlaw or Lexis.
