Which Amazon service do I need for simple querying of book titles, ISBN, and publishers?

Question

There are so many services now, and a lot of search results about the topic talk about services that have been deprecated. I'm only doing this for the first time now. I have a little library app in C# that I want to use to query Amazon services to update book cover picture, ISBN, authors, etc.

Answer 1

You probably want the ItemLookup operation of the Amazon Associates Web Service (previously called the Amazon E-Commerce Service). More info here and here.
