Nerval's Lobster writes with the widely-reported news that Google plans to acquire from publisher John Wiley & Sons the Frommer's travel guides, along with Wiley's other travel-related publishing assets. "This marks Google's second purchase of a popular guide in less than a year.

Zagat scores and summaries now appear in the Google+ Local tab (present on the left rail of the Google+ profile page). Google's acquisition streak reveals a particular conundrum facing tech companies that offer travel and location services: you can assign thousands of the world's best software engineers the task of creating a simple, intuitive interface for ferreting out the best airline fares or restaurants—but sooner or later, you'll need to fill that system with reliable content."
