Of course, there are many web sites that offer long, long lists of links to
other pages sharing the same interests. Most of them are quite good too...
However, I feel that those long lists sometimes are overshooting their mark, as
the comments often are short and not really helpful in determining where to find
extra information. What I will offer here are selected links to sites I find
interesting - I will not try to be complete here. My good friend Menno Putman -
find him under Dutch
collectors - does a fine job if it's completeness you are looking for.
If you want to be included - drop me an e-mail.
