Those of us who discovered DL during the days of AD&D, before the advent of The Chaos Wars, are apt to be sorely disappointed by the lack of substantial War of the Lance material. The Pre-Cataclysm period also gets barely a nod. Although Krynn is every bit as engaging a world as Toril, you'd never guess by comparing the two campaign settings.
That said, if you're looking for a War of Souls or Age of Mortals era campaign, this book provides a decent starting point. Excellent racial information, plus a few very useful prestige classes, combine with regional information to create a solid groundwork for campaigns anywhere on Ansalon. Unfortunately, it is difficult at times to connect the various regions geographically; political maps are small in scale.
Where the DL CS truly shines is as a general reference for DMs and players alike. It seems that WotC put this book together intending the information within to be used in non-DL campaigns. The aerial combat section is detailed exquisitely, and there are enough tidbits of mythology to help flesh out homemade societies in other worlds. Lots of campaign ideas in here, even for non-Krynn DMs.
Ultimately, it's good that the folks at Sovereign Press are putting out further DL references for edition 3.5; as a campaign setting, this volume barely scratches the surface.
