unopened guide

Reading all the posts of this site has really made me realize there is a lot more to learn about unopened material. Is Mark Murphy`s old unopened guide still the best resource out there, besides tuning into this message board?

There also isn't a comprehensive guide to the variations within each year in terms of wrappers, nor definitive info on how many cards per pack, what cards can be found within certain wrappers ('59 Fleer having #68 in one type of pack, but not the other, for example), what, if any, wrappers were used in years other than their main issue, etc.
Would be nice to assemble that knowledge in one place and either prove or disprove commonly held beliefs.
Always looking for Topps Salesman Samples, pre '51 unopened packs, E90-2, E91a, N690 Kalamazoo Bats, and T204 Square Frame Ramly's
The book is a good beginner's piece but as has been mentioned there's a TON not in it. Google search old CU threads like the stars on top cellos and there's a wealth of valuable information in there from some great board members.
