... Cetacean Scifi

This morning I finished reading Startide Rising by David Brin. The basic story involves an earth ship crewed by humans and uplifted dolphins and a chimp, hiding out on a world as representatives of various "mature" galactic species fight over who will claim them and their important discovery.
The world building is excellent and the waterworld is a joy to read about. Also great was the dolphin language and psychology and their struggle to stay true to their relatively newfound sentience. In the end I found it unputdownable and delayed my trip into work by another ten minutes just to finish it off.
Of special interest to LibraryLand is the subplot about the Galactic Library which each species is given access to as they gain sentience. It is a high ideals concept that has suffered from the Galactics giving earth a somewhat edited and even falsified version making it as trustworthy as some people think Wikipedia is. It also brings to mind the idea, that staff talk about every now and again, of getting rid of not only the unused books but also the "incorrect" books, one example being the multitude of diet books with suspect nutritional advice.
Should librarians be the arbiter of what is worth being in the library? And if not then who should be?
