Lecturers will recommend books at the start of their lecture and will often highlight one or two as the most relevant. These then become the most popular so while John’s has a good library these books will always be in high demand, so you may want to buy copies of one or two key books. We’ve mentioned a few of the ones that are generally recommended on the page for the more relevant courses. John’s gives a book grant to all students for up to half the cost of all academic books – more information can be found at:

In Part IB and Part II you tend to find that more and more of the books you need are located in your department library. The catalogues for college, departmental and university libraries can be found online at:
