Since the deaths of István Bibó and his wife in Spring 1979, their family bequest has been enlarged with the addition of a large number of memorial items: photos, publications, videos, and other records. Art historian István Bibó Jr., as the main voluntary caretaker of the family collection, himself contributed all these materials fairly creatively, and he devoted a great deal of time and energy to collecting and preserving his father’s legacy. The original family collection by now has been enriched by many new memorial items. Thus, it has become a unique source for research on Bibó’s reception in Hungary and worldwide. Among the memorable events of the four past decades, the centenary of István Bibó's birthday in 2011 was of particular importance. It included several commemorations, workshops, and conferences, and many studies and books were published, interviews were done, films were made, and exhibitions were organized. These materials constitute a distinctive sub-collection of the Bibó bequest. A brief chronicle of the year, an invitation card, a photo, and a conference opening speech held by István Bibó Jr. may well give an air of the “Bibó Memorial Year.”
