The stories are a good read, notwithstanding my earlier comment about the dated feel of the prose. I fell a little let down by the failure to tackle some of the more important paradoxes of time travel. It reminded me of a comment at a worldcon once about how Star Trek plots were all about how to avoid using the matter transmitter to solve all of the problems. Anderson does not do this. This, while not making for compulsive reading, is hugely enjoyable in small doses.
Small doses is what the short story format provides.
Ultimately, I have no real beef about this book.
