Query: a little more help would be nice

It was a very informative book, but I guess you would almost have to have been an avid collector to understand it. Really, it should have been done to make is easier for the beginning collector to understand. I have markings not in the book and the companies and markings are all scattered. My oppinion they companies marking should have been together with the different years they used that mark. and if there were extra marks used with that company when were they used and why. not at all helpful to me, maybe after i can siphon the books code to understand it better it will be more helpful. sorry just being honest as I am new to collecting and would like to better know what to look for.
