Regional Research Library in Liberec, Public research library in Liberec, Czech Republic

The Regional Research Library in Liberec is a public library in the center of Liberec, in the Czech Republic. It is spread across several floors and includes sections for periodicals, children's books, and multimedia materials, along with computer workstations and a café.

The first library in Liberec was founded in 1759 by dean Anton Kopsch for young clergy. On 26 May 1923 Friedrich Jaksch founded the Bücherei der Deutschen, taken over by the Czechoslovak state in 1945. A 1954 fire at U Věže destroyed 250,000 volumes; the research and popular libraries merged in 1958 and physically in 1969. Radim Kousal's SIAL building opened on 9 November 2000 on the site of the synagogue burned in 1938.

The library regularly hosts exhibitions about the Liberec region that anyone can walk in and see. These displays tend to focus on local stories, people, and everyday life rather than broad national themes.

The library is easy to reach on foot from central Liberec and is clearly signed from nearby streets. It is open most weekdays and on Saturdays, and internet access is available to all visitors without registration.

The library holds a collection of rare regional publications and archive materials that document the history of Liberec and the surrounding area. Many of these items are not available anywhere else, which makes this a useful stop for anyone researching the local past.
