If you get in Oxford, you will find out, that everyone has several pet tomes they like. My weapons of choice for Finals were:
2. Norman & Coxon
1. Cotton and Wilkinson
2. Greenwood and Earnshaw
3. Shriver and Atkins
4. A myriad of library books, about each specific column in the periodic table.
2. Dill and Bromberg - Molecular Driving forces
4. A bunch of specialist books, for each topic.
Almost all of these, except some of the biggest tomes, I took out from the library.
