Thanks for the pointer to 3D Cafe. I had browsed a bit there before, but never tried their useful "search" feature. Lots of books there, in 3DS (which I know how to get into Poser 4 on my Mac) and WRL (which I haven't done, but should be able to, I'll try tonight). No notebook found by "search". Three briefcases found, one in 3DS (OK); but the others in PRJ and COB formats, and I do not know how to get them into Poser 4 on my Mac. Any suggestions appreciated.
