Openbare Bibliotheek Amsterdam
The Openbare Bibliotheek Amsterdam (OBA; ; English: Amsterdam Public Library) is an organisation of public libraries in Amsterdam, Diemen and Ouder-Amstel in the Netherlands. The first library opened in 1919 at the Keizersgracht in Amsterdam. As of 2018, the OBA had 26 branch libraries, 177,000 members, and 1.3 million objects in its collection.

History
The first public reading room and library of Amsterdam was opened at the Keizersgracht on 8 February 1919. The Central Library was opened at the Prinsengracht in 1977 and moved to the Oosterdokseiland in 2007.

The video podcast This Week in Libraries (2010–2014) was recorded in the Central Library.

The OBA was selected as the best library of the Netherlands in 2012.

Collections
As of 2018, the OBA has a general collection of 1.3 million books, CDs, and DVDs. The library also has a number of special collections with books about the history of Amsterdam, children's books from the 17th–21st century, and books from the Dutch authors Gerard Reve, Hella Haasse, and Boudewijn Büch.

Branches
The OBA has 26 branches in Amsterdam, Diemen, Duivendrecht, and Ouderkerk aan de Amstel. The largest branch is the Central Library or OBA Oosterdok at the Oosterdokseiland, just east of Amsterdam Centraal station.

Central Library

The Central Library or OBA Oosterdok has a floor surface of 28,500 m2, spread out over 10 floors, 1200 seats, of which 600 with Internet-connected computers and a staff of 200. Also included are an auditorium, an exhibition room, the Library Museum, the Gerard Reve Museum and 2000 parking spaces for bicycles. On the seventh floor is a V&D La Place self-service restaurant with a south-facing terrace.

The cost of the project was €80 million. The building was designed by Jo Coenen, the former state architect (Rijksbouwmeester) of the Netherlands, who also designed the nearby KNSM Island, as well as the Central Library of Maastricht, and renovated the distinctive Glaspaleis in Heerlen, which houses its Central Library.  Arup were selected to create the lighting design to create "a landscape with different zones" and a system for distributing fresh air which cools the building through drawing in the cold air outside.

The Central Library is open 7 days per week from 10 a.m. to 10 p.m. and the lending and returning of books is fully automated. Not only does the OBA provide a large range of printing and copying facilities, but some other unusual features can be found in the library, such as two radio stations. AmsterdamFM is located on the first floor and OBA Live is on the fourth floor. Both radio stations have live broadcasts where the public is welcome to watch.

The Muizenhuis made by Karina Schaapman is located in the youth department. It's a doll house for mice, made almost entirely by hand. This Muizenhuis, or Mouse House, is the decor for the adventures of two curious mice called Sam and Julia.

The library has an exposition area which features rotating expositions related to design, art and/or books. All the expositions are open to the public for free.
