For the plastic surgery years, a nice book to keep in your bag is 'Essentials of Plastic Surgery' by Jeff Janis, out of UTSW. Its small enough to fit in your bag for ED calls, and its got a nice quick review of just about everything you'll see in the ED or OR, or just to skim right before grand rounds or case conferences.
For the general surgery years, I've done really well studying for the ABSITE with 'The Surgical Review' by Atluri. Its pretty easy to read a whole chapter in an evening, and there's a chapter for each rotation you'll do during those years. You can read the whole book in the several weeks before the ABSITE and do just fine each year.
There are just so many plastics books out there that there's few that will have everything you'll need. Your library will surely grow over the next several years, and there are some others that would be nice to collect: Mathes of course (8 volumes); a book on local facial flaps and there are two good ones, one by Ian Jackson, and another by Shan Baker; surgery of the hand by Greene (2 volumes); Breast surgery by Scott Spear (2 volumes); Surgical Approaches to the Facial Skeleton by Edward Ellis and Michael F Zide.
Its a start at least!
