This Collection came to the Archdiocesan Archives in Ljubljana (AAL) in 2007 from the Institute of Saint Stanislaus, where it was safeguarded until Archbishop Šuštar’s death in 2007. It was systemized in the period between 2007 and 2008 by Sister Mira Rožanc, who took care of Archbishop Šuštar during his retirement between 1997 and 2007. The Collection will be fully opened to the public in 2057, but access is already possible.
