After cremation, his ashes were taken to Vienna and buried at Lainzer cemetery adjacent to the [[ORF (broadcaster)|ORF]] Centre, where his wife Josefine Anna Popper (called "Hennie") had already been buried. Popper's estate is managed by his secretary and personal assistant Melitta Mew and her husband Raymond. Popper's manuscripts went to the [[Hoover Institution]] at [[Stanford University]], partly during his lifetime and partly as supplementary material after his death. The [[Alpen-Adria-Universität Klagenfurt|University of Klagenfurt]] acquired Popper's library in 1995. The Karl Popper Archives was established within the Klagenfurt University Library, holding Popper's library of approximately 6,000 books, including his precious bibliophilia, as well as hard copies of the original Hoover material and microfilms of the incremental material.<ref>{{Cite web |title=Karl Popper Archives |url=https://www.aau.at/en/university-library-klagenfurt/karl-popper-archives/ |access-date=3 January 2023 |publisher=University of Klagenfurt}}</ref> The library as well as various other partial collections are open for researcher purposes.
