Here's the 2014 guide: http://docs.autodesk.com/ACD/2014/ENU/
Don't bother - it is the same abomination that the 2013 guide is, proving once again that Autodesk is a magnificent case study in how to stuff up a website.
At least they provide a .chm file in the SDK that you can use and search in. Autodesk, please don't break that too.
"Search is your entry point to Help."
For Autodesk, it seems that search, and the distinct lack of reasonable navigation (e.g., outline/table of contents) is not an entry point, it is a deliberate barrier, rather than a product of deficient or bad decision making. That idea is based largely on the theory that Autodesk is very deliberately targeting new users of AutoCAD, as part of a systematic effort to discourage them from learning and becoming comfortable with using it, as that makes it much more difficult to coerce them to abandon it and switch to another Autodesk 'replacement' product.
Unfortunately, that tactic has a major downside for more than just noobs.
If you haven't noticed, the online help for non-AutoCAD products and AutoCAD verticals seems to conform to a completely different and higher set of standards.
Of course, a tactic like that lends itself to the widespread perception and belief that plain 'vanilla' AutoCAD users are, in the eyes of Autodesk, second-class citizens, in spite of the fact that they are responsible for the lion's share of their revenues.
