A concise reference ‘cookbook’ guide for developers who want to integrate ‘free’ public data into their website or application, Pete Warden provides a guide to the APIs. The organisation of the book is quite logical, based on the subject of data you want to work with, such as websites, services, information on names of people, search APIs, and so on.
It’s useful, perhaps not a book you would refer to constantly but a good source of reference for those who rely on external information to enrich their existing solution. The book is quite short and perhaps could do with a bit more in terms of other third party APIs, and a lot of the APIs are only useful for the U.S, but other than that, I would rate this book quite well. I did enjoy the author talking about whats good and not so good about using each of the APIs, which is a time-saver.
