To find books, e-books, DVDs/Blu-Rays and other items in the library, you'll need to use Library Search. Library Search enables you to search the library catalogue and also some journal databases - you can search by keyword (topic), author or title.
The Very Short Introductions series from Oxford University Press offers concise and original introductions to a wide range of subjects. Each volume provides an authoritative overview of a concept, field, or body of work, drawing out the central ideas, themes, and approaches, so they are useful background reading if you are writing a feature on a particular topic.
