Reference books, such as encyclopedias and handbooks, are good starting points for research. They may be available in print or online. They can help you refine your topic and select words and phrases (search terms) to use in your searches. The Oxford Dictionary of Geography is available online through the Douglas College Library.
Use the Library Catalogue to find other books. Begin with a KEYWORD search using words and phrases that describe your topic. Library catalogues are all structured in the same manner, so once you know how to use one library's catalogue, you'll be able to find material in any library.
