HTMI hosts the largest theatre library in the country. The collection has two parts: a specialized library and a press archive. The library has over 80,000 volumes. A partial digitization of the collection started within the frame of special grants (NKA, MANDA). Another very important and often used source about performances from the past is our collection of press cuts: mostly reviews and interviews, but also many other theatre-related articles. This collection is frequented by both researchers and theatre makers, preparing for a new performance of a given play. We preserve over ten thousand folders of performance reviews organized along performances, authors and we also have a separate collection on theatre makers and playwrights, as well as performing arts institutions. Retrospective digitization of the press archive is also very intensive and, from 2007 onwards, we only collect articles in a digital format.
