You'll find plenty of scholarly texts in the library, discussing an artist's work, a specific technique, etc. But you can also find books full of large images. Some might me a mix of scholarship and images, some are primarily photo prints. As always, when you do research consider who is speaking, what their bias might be, and whether or not you should be seeking out the voice of the artist themselves.
Anthology: Contains work from many artists, sometimes a comprehensive theme like "icons of the 21st century" sometimes more specific like "Food Photography". The book will feature many artists, sometimes multiple authors, and an editor to pull everything together.
Monograph: This is a book all about one photographer. There are even different types of monographs:
Exhibition Catalog: Accompanies a museum or gallery exhibition. Often it's a paperback catalog meant for practical purposes as people visit the exhibit, but with enough interest it could also be published as a hardcover book to be sold widely. Tip: include filetype:pdf in your Google search to limit your results to just PDF catalogs you can view entirely online.
Artist's Book: A book that not only contains artwork, but serves as a work of art itself. The form of the book is part of the concept and aesthetic of the project.
