The Theatre Museum is part of the Netherlands Theatre Institute and shows the history of Dutch theatre by offering a collection of costumes, drawings, prints, puppets, props, and sets. One of the most interesting sights is the carefully restored home theatre of Baron van Slingelandt that dates back to 1781. The Theatre Institute organises regular debates and workshops, and features an extensive library of plays, music scores, and international magazines.

Each fall TIN publishes the Nederlands Theaterjaarboek, containing information on premieres, tours, guest appearances, festivals and graduates of the previous season, including addresses and ample indexes. Several books of essays are also published each year, usually in Dutch but sometimes in major foreign languages. There are also compact discs of historical recordings from celebrities of cabaret, opera and popular entertainment. Although TIN does not publish plays, it collaborates with some foreign publishers in the production of anthologies of contemporary Dutch theatre. You can find editions in French, German, English, Portuguese, Spanish and Italian. The Theatrer Instituut also supports the series of Dutch plays in foreign languages, published by International Theatre and Film Books in Amsterdam.
