LibSearch is the search system of the VU University Library. It allows you to search not only the holdings of the VU Library but also the collections of libraries worldwide. LibSearch is especially useful for finding (digital) books, which you can either access directly through LibSearch or reserve. Make sure your student card is activated as a library card if you want to reserve a physical book.
How to search in LibSearch is explained in the short video (2:17m) below.
