Why be embarrassed? I for one would love to hear what old sf book or collection you've been flipping through. (And Old Twentieth is recent, and by a respectable writer as well!)
Myself, I've actually been perusing some of the "Isaac Asimov Presents the Great SF Stories" paperbacks that came out during the 80's. Found three in a used bookstore. When they were coming out I turned my nose up at them, partly because I was already familiar with most of the stories, partly the perceived tackiness of the series. (And by the second half of the 80's I was going through a non-sf-reading phase, though I didn't know it was a phase at the time.) Now I marvel at what a good deal these books were; for the price of a cheap little paperback you could get a more than decent little anthology of some of the best sf stories of a particular year, from the late 30's to the early 60's. Wish I'd bought them at the time, though I probably would have sold them by now.
