If, like me, you lament the state of science fiction today, and if, like me, you long to read stories that will transport you back to the days of the masters of "hard" science fiction--writers like Arthur C. Clarke, Robert A. Heinlein, Hal Clement and Malcolm Jameson--then this thick volume could be just what you're looking for.
In general, I find today's science fiction unreadable. Every once in a while, out of desperation, sheer boredom or an attack of unwarranted optimism, I pick up a new-release SF paperback, or check one out from the library. I am invariably disappointed. Some current SF books I can't even finish, whereas I continue to read the old ones over and over. I can't recall ANY memorable SF books written within the last 20 years. In my humble opinion, there are very few recent books that even begin to compare to the "hard" SF classics like "Space Cadet," "The Deep Range," "Mission of Gravity" or "Bullard of the Space Patrol," to name just a few.
"The Hard SF Renaissance," however, gives me some hope that all is not lost. If you're a fan of "hard" SF, the stories in this book should appeal to you. While I don't agree that they collectively presage a "renaissance" of the "hard" SF style, they are nonetheless all quite good and live up to their billing. I commend this volume to you if you want to read good, "hard" SF without having to pull out an old, dog-eared, brittle 1950s classic from your collection.
