There are several good travel guides for visiting Delphi; these can help you plan your trip, including the details that sometimes get lost in the big rush of booking air travel and the like. In addition, Delphi is listed as a “must see” site by many books listing just such sites.

For example, Delphi is considered one of the “1,000 Places to See Before you Die” and it’s considered one of the “Frommer’s 500 Places to Take Your Kids Before They Grow Up”.

Now, if you’re interested in history, pick up a copy of the “Holman Bible Atlas: A Complete Guide to the Expansive Geography of Biblical History”, or “The Road to Delphi: Scenes from the History of the Oracles”.  "Delphi: A History of the Center of the Ancient World" by Michael Scott is a recent (first edition came out on 2014), very comprehensive read too, while many interesting Delphi guide books are available both online and on the spot.
