How to create API's book

Question

Are there any good books that concentrate just on API's at the enterprise level. Preferably in JAVA but any other language will do as well.

I looked on google but was not able to find books that just concentrate on API design.

Answer 1

Have you tried amazon:

http://www.amazon.com/Practical-API-Design-Confessions-Framework/dp/1430209739/ref=sr_1_fkmr0_1?ie=UTF8&qid=1281462598&sr=8-1-fkmr0

This is also an interesting case study:

Found it, this book was very helpful:

Answer 2

Also, "Framework Design Guidelines", which is a .NET book (not what you are looking for), but has some good tips/advice too.
