There are many ways to go about gathering the information you need. In most respects they're the same methods you would use to research any other subject, whether it's for a school report or a historical novel. There are a large number of resources available; you just have to apply yourself to making use of them.

1. Libraries

A good starting point for any research. If you don't find what you need on your own, ask the reference librarians. That's what they're there for; they're trained to help people locate information. Depending on your subject matter, encyclopedias and other reference books might suit your needs. For more up-to-date information — for example, for the latest in scientific research — browse the periodicals.
