Barbara has just commended the forthcoming edition of a book which I have found useful in the past -- but it occurs to me that many readers of this blog do not have large budgets for expenditure on lawbooks, particularly if they can't be 100% sure that they'll need the book before it's replaced by the next edition. BUT ... review copies are free, so long as you write a review.
What this blog needs is a book review editor, who can build up (i) a list of readers who want to review IP books in areas of their interest or expertise and (ii) a list of publishers who want their books to be reviewed. Then all you have to do it put the two together. Any volunteeers?
