3D modeling
I use Sketchup and I love it (I use a standalone, installable version from 2015, not todays web version)
Sketchup Timber Framing Tools (former TF Rubies) by Clark Bremer. These make it super-easy to design and model timber framing joints.
The 2D version of Dietrich's PlanCAD-L program is free
Broad overview over existing software options given by Alex Schreyer
Books
Jack A. Sobon: Historic American Timber Joinery: A Graphic Guide, 2004-08
Tedd Benson: Building the Timber Frame House: The Revival of a Forgotten Craft. This text is from 1986, so it's a bit dated, but inspiring read nevertheless.
Book shop of the Timber Framers Guild
Book store of the Carpenters Fellowship (you'll also previous issues of the club magazine with significant articles)
Das Holzbau-Buch, a 100 years old classic.

Das neue Buch vom alten Wissen der Schiftung (also available in English)
Tage Frid's books are super inspiring for woodworking in general, simple, didactically very well presented.
Ready for more fascinating stuff on old-world woodworking tools and techniques? Read about Roubo and his book L'art du menusier. Not to confuse the hard work of the time with a too-romantic view...
Eric Sloane: Sketches of America Past. Nostalgic Inspiration. The universal use and meaning of wood in former times. (This issue combines three books in one and is a nice bargain therefore.)
Very good, scientific book about Conservation of historic timber structures
There is a fascinating, free online course on Preserving Norwegian Stave Churches by the Norwegian University of Science and Technology (NTNU). It takes a few hours but it's fun and really interesting!

There's a Facebook group called "Historical Timber Framing, Traditional Building and Architecture Group". It's quite busy. *I purposefully re-joined Facebook for nothing else than this group after a hiatus of 10 years, and recommend it!)
