Academic libraries organize physical books using the Library of Congress Classification Outline.This is how you find a book in the library.
The classification system produces a "call number" on each book - an alphabetical and numerical sequence which locates a specific book on the shelf. More about understanding Library of Congress call numbers.
This system clusters books together by topic. If you know the call number range for a particular topic you are resarching (even if you don't find exactly what you are looking for in the catalog) browsing the shelves can often lead you to other, similar books.
Books about volcanoes and earthquakes are shelved in the QE 521 - 545 range.
