I need some info about the sonatas of Scarlatti.

I was wondering, is there a book i can buy or some online resource that has detailed descriptions of those sonatas, including the form used by each (i know some of the form used are fugue, toccata, concerto, dance movements ect.).

This is not performance related, i just need to know for myself. The booklet which comes with the complete Scott Ross edition has some of the details i need but it's not comprehensive enough.

I'd also love to know if there's a way to sort those sonatas chronologically.
