The Library shelves print books according to their subject matter using the Dewey Decimal Classification System (numbers 000 to 999) so that like-material sits in close proximity on the shelf. Broadly speaking, engineering is shelved at 620-629 (see below left); see also computer science at 000-009, mathematics at 510-519, and physics at 530-539; all in the O'Reilly Library.
Copies of all print books are spread between the Main Lending Collection (you may borrow main lending copies for 1 or 3 weeks) and the Short Loan Collection (borrow these copies for 48 hours) according to demand. Check the catalogue for availability.
The Library now has access to over 150,000 e-books, all of which are searchable via the catalogue. When you search the Library catalogue for a title or keyword, you will find that an increasing number of records are for an "e-book". This means that by clicking on the link within one of these records, you can read that book online. Note the option to filter your search results by selecting e-books from the collection menu on the left. If you access an e-book from an off-campus location you will be prompted for your DCU username and password.
