pcoz – challenging to live up to.
RT – no, it is not in print. I wish it was. I have been looking to complete my set for over 10 years. I have seven of 11 volumes, five of which I inherited from my father and grandfather, and 2 of which I found in bookstores in Israel. One place I found one that I can remember is Lichtensteins on Rechov Strauss, #36, I think, but that was at least 7-8 years ago. the seforim were written in the 50’s and 60’s, with a small print run, and the author was a survivor of the shoah from Hungary. It is an alphabetical encyclopedia of every gadol from the time of the geonim through the rishonim (the bulk of those researched) into the early achronim. He brings as much detail as he can, sometimes 10 pages or more on those rishonim for which there is much collative material available, and sometimes only a sentence or two if there is really nothing known but the name. I’ve found these seforim to be an incredible help with my genealogical research into my family, and often an excellent confirmation of sources I have found elsewhere. If you do find it anywhere, please post something in the coffee room to let me know.
