Sample slabs is unfortunately badly out of date. Cam had something like 120-130 samples. David's recent book has 585 (more with the 30 or so he didn't have that I've fed to him, plus more from other readers too).
Lakesammman did an update on PCGS but as we found out above the PCGS site url is being blocked here. You can certainly Google for it (search for "PCGS Generations - an attempted update"), it should be the 1st hit.
Conder's book can be borrowed from the
ANA library (you have to be a member) for the cost of postage both ways.
If you post photos, several of us can give you results from the book plus our collections.
