Most historians publish their work in books. So, for many topics in history, your best starting point is a good recent scholarly book. The easiest way to find that book is to ask someone else who is knowledgeable about your topic -- for example, your junior seminar instructor or spring JP advisor. But a thorough search of the library catalog is also essential. Here are some tips on finding books about historical topics in the Princeton University Library Catalog.
Identify the Library of Congress Subject Heading for your topic, and use it in a subject search. You can look up LC Subject Headings in the big red books in the Trustee Reading Room (and elsewhere in the library). You can also look up a known book on your topic and check the long view for the subject headings assigned to that book.
Use the word "history" as part of a keyword search.
To find material about a person, an government agency, or an organization, search for it as a subject
To limit your search results to English-language materials, "Set Limits" before searching.
Didn't find enough? Expand your search in Worldcat to identify items not held by Princeton, then use Borrow Direct or Interlibrary loan to get the books you discover there.
Who is the author? Is he/she associated with an academic institution?
Who is the publisher? Most good history books are published by academic presses, e.g. Princeton University Press or Oxford University Press.
When was the book published? Your first choice will probably be a book published in the last ten years or so, because a recent book will refer to all the previous work on your topic. But some older books are still very valuable, so do not worry if the most recent book you can find on your topic was published long ago.
Does the book include the scholarly apparatus that will enable you to verify the author's work? Look for footnotes or endnotes plus a bibliography. A book with no notes or bibliography will not be helpful to you at this stage of your research.
Once you have a book in hand, read it. Alas, there are no shortcuts to this part of the research process.
