I would like to see some more advanced stuff on finite p-groups but don't know where to start and which books would suit for that purpose (so far I read Isaacs 'Algebra' and a fair amount of his 'Finite Group Theory').
Does it make sense to have a look at Berkovich 'Groups of prime power order' or is it more like an encyclopedia?
Thanks in advance !
Edit: Does anyone know how I could get Susan McKay's notes on finite p-groups? Seems to be what I am looking for!
Susan McKay's book is available at a very reasonable price, but it probably ships from the UK, so it may take a while to get to you, depending on where you are. See http://www.maths.qmul.ac.uk/~pjc/qmmn/ . I own a copy, and while I have not read it all the way through, I have found it very useful. However, I'd also recommend the relevant chapter of Gorenstein's Finite Groups, which covers Lie rings, which I believe McKay omits. There is also Leedham-Green and McKay The Structure of Groups of Prime Power Order, but it presumes knowledge at the level of the smaller McKay book. However, it is one volume to Berkovich's SIX. Berkovich appears to be a very expensive set of books.
