The Robert Walser Archive invites researchers to visit. In addition to the most comprehensive library on Robert Walser and Carl Seelig, the majority of Walser's manuscripts and a large collection on Walser's siblings, on Walser's reception in literature, theatre, music and art, it also offers an extensive press collection. It also houses the (partial) estates of important researchers such as Jochen Greven, Werner Morlang and Anne Gabrisch. Carl Seelig's estate contains many thousand letters, a comprehensive collection of his writings and an exhaustive collection of his prints.

Researchers can find a temporary workspace, a collegial environment and the opportunity to network with others interested in Walser at the Robert Walser Archive upon request.
