What is a collector of bookmarks called?

I have found 'Bookmarkniatic' which I think is a less than serious term on the following website:
http://palimpsest.stanford.edu/byform/mailing-lists/exlibris/2001/06/msg00178.html

I have not been able to find anything else other than the generalised term of Ephermera, which bookmarks would be part of.

I haven't had any luck in finding a recognised English term for a collector of bookmarks. But according to French websites, the French word is signopaginophile or signetophile, with an additional word chartasignopaginophile for a collector of bookmarks made of paper.

Are these words perhaps used by English-speaking collectors as well?

Judging from the Net, the hobby seems to be quite popular in France. There's even a collector advertising swaps at http://www.chez.com/marquepage/
