The other bookstore was a locally owned one (we had no big box bookstores in Medford when I lived there), whose name I forget, but it was right around the corner from The Craterian Theatre.
I would go there frequently, and I bought most of my movie related books and magazines there, particularly all of the WHATEVER BECAME OF....? books, which I would look forward to each year, or so, that they came out. I think I still have all of those.
I would also secretly check out the new issue of PLAYGIRL each month, which was kept in the women's magazine section way in the back of the store.
