Start your research GENERAL and let the library's resources guide you to keywords, phrases, and names that can make your subsequent searches more precise.
If you have ONE book that looks good, look at the book record in Orbis or Quicksearch and review its LINKED SUBJECTS -- which will bring you to more related books on your topic.
KEEP TRACK of phrases and subjects that have worked for you -- you will want to remember them for later searches.
Imagine yourself in a CONVERSATION. Search for scholarly literature EARLY in your research process and OFTEN, and get familiar with the scholars in your field. Find points and counterpoints to help strengthen your research question.
Your Personal Librarian
All Yale College undergraduates have a Personal Librarian. Find yours here: library.yale.edu/pl
Great to use to books - but remember that Orbis does not have individual book chapters or articles, only whole items! Pro-tip: Try "Subject Browse" from the Basic Search form to identify subjects on your topic.
