This is not promotion but simple truth: the best place to start for La Jolla suggesting reading would be with the three articles TripAdvisor recommends and links to : one from RandMcNally regarding the city in general, one from the New York Times and another from the Los Angeles Times that make for easy, compelling reads as to why one should or should not visit La Jolla.  

Aside from these articles, books abound regarding the background and attractions of La Jolla.  La Jolla, A Celebration of Its Past by Particia Daly-Lipe is an excellent way to glean historical detail to enliven the tourist experience.

There are also books by a couple of Ellens.  Ellen Mills’ Guideposts to History – La Jolla Edition – People and Places of Historical Significance in Early La Jolla, CA is another excellent guide to the city’s past, though harder to find than Daly-Lipe’s contribution.

Ellen Clark’s Hidden San Diego: Including La Jolla, the Zoo, San Diego County Beaches, and Tijuana , though not as focused on La Jolla itself, is very valuable to the future visitor because most all of San Diego’s tourist hotspots are a short car trip away from a La Jolla address.  

La Jolla Travel Information is an informative blog written by a local resident whose goal is to aid visitors in finding local attractions and activities "often overlooked by out-of-towners." The author is an experienced travel writer and has written the Frommer Guide to San Diego as well as many feature articles on La Jolla and San Diego.    

With these books, articles, and blogs in tow, Joe Tourist should have little problem navigating La Jolla, knowing both when to stay and what to check out nearby when checking out.
