Hi, I hope you're excited for Michaelmas!
I'm presuming you haven't actually been set an essay yet, you're just reading some stuff in advance?
I did BH1, so I can't help with course content, however I can give some general advice

- Have you tried contacting your college parents, via Facebook maybe? I wrote to my college mum last year and she was able to point out some of the more useful books on the reading list.
- Generally, you won't need to buy many of the books you need. When you get into the swing of things you'll be breezing through 6/7 books per essay, and you'll rarely need to look at them again if you take decent notes the first time round.
- Therefore, try to only buy books that are collections of essays, or are really must-haves, as in they are THE book for that topic.
For example, before I came up last year, I brought the core texts for my first term of historiography (so 2 books) and then another 3 books, one was a complete anthology of primary sources, one was THE book on Medieval women, and one was a "Very Short Intro" to something which I've forgotten. I found this was a good overview to prepare me for when I arrived, and I didn't buy any more books until the core texts for my 2nd term. It's hard at the moment without access to the university's libraries, but believe me, once you arrive, you will have little need to buy your books

If all else fails, the
Used section on Amazon can be pretty good...
