Service oriented architecture books (SOA books) contain all the basic details you need to know about service oriented architecture.

Service oriented architecture, to put it in simple terms, uses the framework of previous software programs to create unique programs with a lot less work than traditional software designing. This means you can get a software product that is just as good for a fraction of the costs.

There are free SOA books but the best SOA books can come with a price tag. Some books are dedicated to teaching you the basics and there are some books that can teach you how to create service oriented architecture.

If you run a business then it is likely at some point that you will need some software designed that is specific to your business. If you decided to employ people to build your software from the ground up then it is going to cost you a lot of money. If you decide to get it built using service oriented architecture then you can lower your cost and you can get a software program that has the functionality you need and the flexibility to adapt as your business grows and changes.
