A little list of the must-reads and lesser-known SF authors...

At the request of one of last night's dinner guests (a school principal), I went over my SF library for less-known classics, plus neglected and newer authors she might not have encountered but which I can recommend as worthy in some way, by quality of writing, characterization, or interesting ideas. I tend to like harder SF, so this list is skewed in that direction, but if something's really good, genre doesn't matter. And of course I'm leaving out more than I'm listing, but time flies...
