Together with older holdings and some further occasional purchases the collection now numbers over 3,600 titles. It consists of poems on marriages, accessions to office, anniversaries and deaths of Dutch citizens. Poems on monarchs, stadholders, and on historical events are not included, because they are considered pamphlets. Most poems are in Dutch, although Latin is also well represented. The size varies from one broadsheet to reasonably sizeable anthologies of originally separate poems on one single event.
Marriages form the most frequent occasions, followed by deaths.
