I read all the posts... thank you all for this interesting discussion.
I will certainly first use Codehappy method : I had given up collecting for years and just returning now. So when I gived up I emptied all my stockbooks and... put all the stamps in large plastic boxes. All the stamps are mixed. I did that to gain space, thinking that I would never have enough time again to consider stamps collecting (I perhaps have something like 150 - 200 k stamps, counting the duplicates of course)
Anyway the task is huge so the little cards would be a good idea to sort thing first. Then I may search for other means.
I love the idea of self made pages with mounts or hinges but I saw some practical problems with them.
First, the type of paper. The thickness is not a point, it's more the acid free part that annoys me : I would never be sure of the quality. Second point are hinges. I don't want them, even on used stamps : they leaves marks and I feel that they are more a thing of the past than something collectors had to use (everyone has his own view, no problem with that, I am certainly not the keeper of the holy truth on stamps collecting) so... mounts... as it was already said, then you have a page which cost is higher than the stamps on it...
So much for albums, then stockbooks... handy, safe... not appealing to the eyes which was the best point in self made pages... Same things goes with Vario and other same type of pages... even if they are smarter that a plain old stockbook.
I don't consider pages made by seller' they are beautiful but as stated elsewhere, they don't fit the needs of those which also collect things that are not in catalogs.
So... back to the start... I will use the 102 cards, it will needs some times (years ?) then perhap someone will find THE great way of sorting a collection... I would be his or her first customer
