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

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.

From stackoverflow

• How about LINQ to Amazon ;-p

  (see also how it works, and the source)

  DarkwingDuck : Sure, but that in turn talks to a service under the hood. I wanted a service, not an API :)

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

  DarkwingDuck : Thanks. I thought it might be the AAWS but the blurb about the service seemed to focus more on advertising. I'll give it a go.
