For each item make sure you know the name of the physical library, call number, and whether or not it's checked out, library use only, etc.
Call numbers are on the spine of the book; learn how to read them so you can find what you need on the shelves.
No time to go hunting around the library stacks to find the books you need? Use OskiCat's request feature. Once you find the book you want, click (this button will only appear when an item can be requested). Authenticate yourself with CalNet, and follow the prompts. OskiCat will ask you where you want the book(s) delivered to. You will get an email when the books are ready to be picked up (usually within 1-3 days).

Why use Google Books? Library catalogs (like OskiCat) don't search inside books; using a library catalog, you can search only information about the book (title, author, Library of Congress subject headings, etc.). Google Books will let you search inside books, which can be very useful for hard-to-find information. You can then use Google Books' Find in a Library link to locate the book in a UC Berkeley library, or search OskiCat to see if UC Berkeley owns the book. Try it now:
