Adobe Photoshop Lightroom CC Version 1.1 - manual, books etc

Recently acquired this software but am finding the help sources online are referring to other versions of Lightroom. Is there a good source, manual or book that I can refer to or acquire to help me use Adobe Photoshop Lightroom CC Version 1.1? The Adobe help via the app is pretty basic and does not seem to cover much.

Adobe Photoshop Lightroom CC Version 1.1 seems to have a lot of editing tools but without a detailed manual etc you can waste a lot of time figuring them out. Moreover, it can get really frustrating to look at some online help only to realise that the help seems to be for a different Version of Lightroom. Part of the problem I think is all these different programmes have the same name.

My main interest is editing photo's at a basic level - putting colour into black and white etc. Any comments or help much appreciated.
