I have ordered the book few months ago when i was new to Blender and it helped me a lot to grab the interface basics.
For those of “old school”, like me, having a “real” book on the knees (even while surching for preciser answers on the web) is “essential” for a start into a new application.
Just 2 points:
The dolls & guys on this forum also worth a book by their personnal advises
Pictures in the book are barely usefull… because of a “not so good” printing
The online versions of the pics are much better than the printed versions, so where you have trouble following the book due to an image you can check out the larger colored version for clarification. Essential Blender covers a lot of ground - definitely not a quick read but then learning 3D takes time.
