Swiss Institute for Art Research, Specialized art research institute in Weinegg, Switzerland

The Swiss Institute for Art Research (SIK-ISEA) is a research and documentation centre for art in Switzerland and Liechtenstein, based in Zurich's Villa Bleuler on Zollikerstrasse. The villa, built 1885–1888 by Alfred Friedrich Bluntschli for Colonel Hermann Bleuler-Huber, houses offices on the upper floors and reception rooms on the ground floor. The public library occupies an underground extension, while the restoration and photography studio is in a new building on the former terraced grounds.

The Swiss Institute for Art Research was founded in Zurich in 1951 by the art historian Marcel Fischer (1906–1962). Hans A. Lüthy directed it from 1963 to 1994; under him it joined the Swiss Academy of Humanities and Social Sciences in 1971 and was recognised as a research institution eligible for federal funding in 1981. A branch for French-speaking Switzerland opened at the University of Lausanne in 1988, and a contact office for Italian-speaking Switzerland followed in 2010 at the Museo Vincenzo Vela in Ligornetto.

The institute's public library in Zurich holds 120,000 books, journal volumes and audiovisual media on Swiss art and art history, searchable through the Swisscovery union catalogue. Its reading area in the villa's base was designed by Arthur Rüegg, Ueli Marbach and Klaus Dolder and refers to Alvar Aalto's library in Vyborg. Since 2010 an Ufficio di contatto for Italian-speaking Switzerland operates in the Museo Vincenzo Vela in Ligornetto.

Access to the institute is typically reserved for researchers, students, and art professionals who need to consult its collections and archives. It is recommended to arrange a visit ahead of time to ensure you can review the materials you need.

The Swiss Art Archive at SIK-ISEA holds around 19,000 dossiers on artists and institutions plus 200 written estates, including those of Giovanni Segantini and Augusto and Alberto Giacometti. The public reference library, installed in the villa's basement by architects Arthur Rüegg, Ueli Marbach and Klaus Dolder, has a reading alcove modelled on Alvar Aalto's library in Vyborg.
