The largest collection of bookmarks belongs to Frank Divendal (Netherlands) with 103,009 different bookmarks from all over the world, as of 8 February 2010, which he has been collecting since 1982.

Frank has a well organised system to store his book marks. He first sorts them by country, then within a country he separates them into themes, such as bookshops, libraries, tourism etc. Although he collects all types of bookmarks, his favourites are the ones made of paper.
