The Bibliotheca Rosenthaliana is part of the library of the University of Amsterdam:

"The core of the important and comprehensive collection of Hebraica and Judaica from the University of Amsterdam is the library of Leeser Rosenthal (1794-1868). This library, which consisted of approximately 6000 bands, was given to the then City Library of Amsterdam in 1880. Since then, the Bibliotheca Rosenthaliana has substantially expanded by donations and a targeted acquisition policy and is currently among the the largest in Europe. The Bibliotheca Rosenthaliana does not only include a large collection of printed books, the earliest of which date from the 15th century, but also periodicals, manuscripts (from the 13th century), engravings, photographs and archival materials."
