To find books, ebooks and other resources in the library and at the same time search a few databases, use the main search on the library homepage. You may need to search other databases, but this is a good place to start.
This search brings together a collection of different kinds of resources: print books, ebooks, articles, news sources, theses, multimedia resources. Many are available full text either directly or via the Get It button.
Think of your search terms. If you want just a few good things, you can use just one or two terms, but if you want to make your search wider, you can try more terms.
Try, for example:
first nations or aboriginal or native or indigenous or indians
and include other aspects of your topic, such as self-governance, environment, residential schools etc.
