Click on any title to see its book record. This gives you metadata (information) about the book, along with tools to find it, and the information you need to find it in the library. For a paper book, this is Call number and location. For an ebook, it'll give a URL.

The Subject Headings tell you how librarians describe that subject, and link to all other books with the same subject heading. This is very useful for finding more on your topic. These headings are drawn from a thesaurus created by the Library of Congress. It can be problematic, but it's what we use, and what most academic libraries worldwide use.
