I would just go in and asked them. They are very knowledgeable about all the books and where to find them. You can't go there without finding some book you are looking for.
Electronically, you can't, unfortunately because they don't have an electronic system you can use to search. I believe only rare items are archived. They do administer maps so you can find the correct section and staff members on each floor that are happy to help you look. Even if you can't find the exact book they usually have such a wide selection that you'll find something extremely similar.
In person, stop by them and ask for the specific book you're looking for. They're very well staffed and they'll direct you exactly where you need to go.
You cant find out. You pretty much have to go and scan the shelves in the specific area that you are looking for
