I may be able to help you with paper types. Your question on thin or thick papers depends on the issuing country. I speciaize in Nicaragua, Salvador, and Equador, and in all three of these countries thin paper measures .004-.005 and thick paper .006 or higher. A good micrometer, or even better a paper thickness measure(which I use)is vital in determining paper thickness. As for types of paper, including colored papers such as blue paper, I recommend Fundamentals of Philately by Williams. This book is expensive new,but the method of identifying different papers is explained in great detail. One other point, when working with different paper types, and expecially thicknesses, try to use several samples, expecially with earlier stamps, as the manufacturing process was not that exact and many variables can be found.

Hi Tim,
Which country stamps are we talking about? For Australian stamps I once did a lot of man hours worth of study but the results were inconclusive due to non-availability of bulk material needed. I remember that I have posted my finds here at SOR along time back (maybe in 2006) but that discussion is lost somewhere in the older posts however that discussion is alive at another forum and you can view it here : http://tinyurl.com/algf9b9
Someone has taken over from where I left and is doing some purely scientific research into paper types. As for US stamps I am still doing the paper type research but for my own collecting interests as there is nothing available to authenticate my findings. This is one area which Scott has sadly ignored so far. Specialized listing of US stamps is what experienced philatelicts are looking for but even the Scott US Specialized catalog leaves a lot of things unanswered - even if they take pointers from Unitrade it would be wonderful.
The best that I had come across in US stamp paper variations was the price list of late Mr Victor Bove - either he himself did the specialized listings or he got the help of some experienced philatelist or he bought the stuff from someone who knew about it. I did but a number of paper type varieties from him and was looking forward to adding a lot more of them in my collection but his passing away has left me floundering with eBay and other auction site sppecialized listings - which are not that many.
If someone finds a dealer listing US varieties please do let me know so that I can restart and build on this. I'm talking about the modern US paper varieties after the Washington-Franklin series, earlier than that most US stamps are hard to obtain as mint (a pre-requisite for paper variety of older stamps) and most have a few printing/paper variations.
Canada paper types/tagging types are mostly all listed in Unitrade and therefore are available with sellers at a premium. I plan to work on my accumulation of Canada later this year to find out the varieties listed. I am almost done with US and am left with 50,000 plus US stamps (mostly definitives) in a hoard which I'm planning to sell as a bunch
Ths US 'Blue Paper' varieties of the early Washington-Franklin era are not often seen and also very hard to identify, even if you are sure that you have one you will have to get it certified which is always a risk as many of the used ones with black or blue cancel looks like to be on 'Blue Paper' - the paper is not blue in color but it has grey fibres imbedded in it and looks grayish at the back therefore mistakes are made.
Ii will check my Aussie Paper Type posting here at SOR and maybe revive it.

Auctions - Approvals
I was just enjoying reading through the discussion on another thread on color identification and thought another thing that I would really appreciate help with is identifying types of paper. When I'm looking at a stamp I get really confused as to wether it is thin paper, thick paper, blue paper or blue stamp where the color has run into the paper etc. Could some of you more learned people assist with this?
