16th edition. Loose-leaf, ready to be put in your binder. The main advantage of buying loose-leaf in my view is that you can take just the chapters you are currently using with you to class yet be able to have it all fully assembled for later reference.
Book appears new, in somewhat torn shrink-wrap. I base this largely on the fact that the binder holes are very crisp.
If you want to combine shipping on books I am selling, please contact me before you pay so I can adjust the invoice. (This also applies to books my mom is selling -- look for things from Reno, NV -- she has other accounting books for sale.)
