Sometimes Google Books has an extensive preview of books with pages removed at random. If it's a collection of short stories you can read several individual stories.
The Treasury of Avram Davidson is like that:

Before you start reading, scroll down and make sure the entire story is there. There's a notice whenever pages are missing.
Also, I mentioned this in the what are you reading thread, but Connie Willis' novelette,
Fire Watch, is available at the Infinity Plus website:
