There are a number of ways to find what you're looking for in the library. You may always ask a librarian at a service desk or schedule a consultation for an in-depth one-on-one research session. Below are few tips to get you started on your own, if you'd prefer that.
If you want to browse the books on the library's shelves by topic, you can look for your topic in the Library of Congress Classification Outline then use the call number range it shows to find the section in the library's physical collections. If you're wanting to browse for children's books, look for your topic in the Teaching Resource Center's Guide to Useful Dewey Decimal Numbers.
If you would prefer to use the library catalog to search for titles, you can use the default keyword search option of "All Fields" or you can limit to "Subject", "Title", "Author", or other choices if you want to narrow your search.
You may also narrow your search by various facets in the "Find materials by" column. Using facets you can greatly limit your results without ever having to type any search terms -- see below for an example of using all the facets at once, but you can use any of them you want, or none at all.
If you're not finding what you want, please ask a librarian or schedule a consultation for an in-depth one-on-one research session.
On the other hand, if you know of a specific book, movie, album, map, etc. that you want but the ECU Libraries do not appear to own it, please request it for free through the interlibrary loan service -- we'll attempt to find it and borrow it from another library for you for free.
