I've seen a lot of people recommend Authoring a PhD by Dunleavy as well.
On this note, the reviews on Amazon seem to indicate this (Dunleavy's) is a good book for arts/social sciences - I'm in natural/medical sciences so is Phillips' general enough to be applicable to me? I've also been looking at "The Unwritten Rules of PhD Research" by Rugg and Pat Cryer's "The Research Student's Guide to Success" - anyone used these? I don't need a book with loads about getting into uni, I've done that bit - I'm more interested in something from Day 1 of the PhD onwards, planning, doing the lit reviews, hints and tips for as you go along. Any advice appreciated (up)
