P.S. DO NOT BUY any of these books. They are all available from your medical school's library. The only books I have purchased this year are not on the recommended reading list, because these books are so widely available.
P.P.S Textbooks are not essential for the first year at Barts. You hear stories of fellow students not visiting the library till third year. Yet, if you want relatively good grades, I'd heavily imply that you need to support your learning. As a graduate, I am so use to turning to several sources, not just lecture notes, that it is hard to break the habit.
P.P.P.S. But if you are reading this list, it means you have already opened you mind to the use of textbooks so ignore above.
Essential Books from the Reading List
In my opinion, these books are essential for your first year at Barts and The London SMD.
Clinically Oriented Anatomy by Moore
A good anatomy textbook is key. While lecture notes are enough for content, you sometimes need that second point of view to help cement that knowledge. I would highly recommend Moore but can now see why Clinical Oriented Anatomy is too big. Essential Clinical Oriented Anatomy is much better suited for the course and easier to carry around. It's definitely not pocket size but it's lighter on the rucksack, without lacking key knowledge.
Medical Physiology by Boron
I glanced once at Boron. The layout looked awful and I went in search of other physiology textbooks instead.
Books that you may need if you are weak in a certain area.
For first year, these books are just not worth your time. Too much knowledge or lack of relevance.
More physiology than anatomy. If you are using the other textbooks above, you don't need this at all.Stryer but to be honest, you lecture notes will be good enough for biochem.
