I bought Vol 1 & 2 and a Veterinary volume as well.

I intend to sell them on (I am not a pharmacist and bought them for
purely mercenary reasons). I have a couple of questions.

The Veterinary volume shares the same ISBN. Is it part of the same
publication or more to the point should it be sold separately or would
a buyer expect to receive  all 3 volumes as part of the package.

Aside from the obvious ebay can anyone point to any other likely sales
outlets.
