This paper presents the project “Digitisation of old and rare material from the Bauer Collection” of the library of the Museum Documentation Centre (MDC), which in the first phase relates to the digitisation of the manuscript bibliographic unit Bibliography and material for art and similar disciplines. The unit comprises 31 books that combine bibliographic, biographic and documentary records from the area of cultural history, particularly the history of the fine arts and historical museology from the 19th century to the 1950s from Croatia and other parts of the former Yugoslavia. These records are a unique document of exhibition events and a point of departure for diverse investigations in culture studies, art history and museology. A description will be given of the first realised phase of the project, published in 2008 on the MDC Web site (http://antunbauer.mdc.hr/) with accompanying texts, search engines and digital copies. The second phase, currently underway, will be presented; this relates to Web presentation and virtual contextualisation of a unique manuscript about stechaks of 1949 by Ivan Rengje and the connection of the MDC project with other heritage portals of similar depositary/digitised records.
