• Idiom viewing hours are Monday to Friday until 7:30pm and Saturday 1pm-5:30pm, with no viewing on Sundays
• Weekend puppet shows run October to May in the basement theater, which has its own entrance on Žatecká Street and sells tickets separately
• Sundays and Saturday mornings are unstaffed, and entry then needs a valid library card issued to someone over 15

Prague's main public library fills a 1928 building on Mariánské náměstí. In the foyer stands Idiom, a column of 8,000 books built by Slovak artist Matej Krén.

The children's department has a reading corner for kids and parents, and the basement holds an Art Deco puppet theater with seats that raise up for the youngest audience. The library's own cinema also screens films for children.
