What I have learned so far:

Base Pd object reference list
To learn and interpret Pd I made a quick reference of the basic objects
Base Pd object reference list in Open document format
Same as the above but editable format
Pd extended quick reference list
An object list for the extended 0.39r3 release. It became a bit unwieldy, so I stopped refining it for a while. And I found the object I was looking for...
Documentation and examples of tclPd, the expernal which makes writing objects in Tcl possible.

Of course it is just as free as any Pd doc...
