In addition to its Library, the ADLER Society has in its possession certainly the most significant Collection of Obituaries and Memorial Cards that exists in Austria. It contains approximately a half-million alphabetically-sorted death notices and other family news (mostly engagement notices). The German-language name of the Collection ("Partezettelsammlung") is derived from the traditional Austrian word for a death notice ("Parte"), which comes from the Latin "partir" and Italian "partire", which translate into English as "to depart". Currently, there are a number of projects underway to both compile an index of the Collection and to scan these invaluable historical papers.
The Collection was begun at the end of the 19th century and contains notices from the early Biedermeier period (1790-1800) until today. Since then, some private collections have been added to the Collection, bringing to it death notices from newspapers that approximately cover the timeframe of 1923 to 1938.
The ADLER has also started significant collections of letters of nobility, seals, and seal impressions.
