I've just downloaded the IBM Lotus Notes 8.5 User Guide by Karen Hooper from PACKT Publishing and will be reviewing it shortly - it's going to take me a little while to make it through the 296 page tome.
My first impressions though are good, very good. This isn't a book for developers wanting to learn XPages. It's a book for the users in your organisation, something that has been lacking in the notes world lately.
You can obtain copies of the book at the PACT Publishing Website (http://www.packtpub.com/).
Stay tuned, I'll have the review here shortly.
