If you're looking for series books, there are two I like by the same author. The Dragonriders of Pern and the Talent series by Anne McCaffrey.
With Dragonriders, you can find the original trilogy in one volume. There are many other, peripheral books that tie in to the trilogy, all set in the same "world".
The Talent series has the following titles:
To Ride Pegasus
Pegasus In Flight
Pegasus In Space
The Tower And The Hive
There's a bit of a time gap between Pegasus In Space and The Rowan but all take place in the same "world".
I just finished reading Pegasus In Space and, after the move, will have to hunt up the others in the series.BS (Cee64D) 48
