In 1991, the tricentennial of its opening to the public, the Ducal Library was renamed for Anna Amalia, Duchess of Saxe-Weimar-Eisenach, who arranged in 1766 for the courtly (hoefische) book collection to be moved into the library.

The main building is the Green Castle (Grünes Schloss), Anna's residence, which had been built between 1562 and 1565.
The architect was Nikolaus Gromann.
The dowager Duchess had the building converted into a library in 1761.
The Duchess, seeking a tutor for her son Duke Carl August, hired Christoph Martin Wieland, an important poet and noted translator of William Shakespeare.
Wieland's Shakespeare volumes formed the core of the collection.
From an architectural standpoint, the library is world-famous for its oval Rococo hall featuring a portrait of Grand Duke Carl August.

One of the library's most famous patrons was Johann Wolfgang von Goethe, who worked there from 1797 to 1832.
The library also includes the world's largest Faust collection.
The Duchess's significant 13,000-volume music collection is also available in the library.

In World War II, most of the collection was housed elsewhere to preserve it from Allied bombing.

Today, the library is a public research library for literature and art history.
The main focus is German literature from the Classical and the late Romantic eras.
