In 2006, after making a case to the Museums, Libraries and Archives Council (MLA) for housing the collection, Worcestershire Record Office was identified as its new permanent home.
A project is currently underway to catalogue the collection according to the International Standard for Archival Description (ISAD(G), making it fully accessible to the public for the first time.
It also includes unique records relating to the building, decoration and furnishing of Croome Court and the creation and development of the parkland surrounding it, which was Lancelot "Capability" Brown's first complete landscape work.
In 1938 part of the collection was sent to Birmingham Reference Library on permanent loan by permission of George William, 10th Earl of Coventry.
Around 25,000 documents were sent to the Library, including the official papers of Sir Thomas Coventry, Lord Keeper of the Great Seal of England.
The collection was returned to the Croome Estate Trust on 28 February 1950, although Birmingham Reference Library retained the papers of Lord Keeper Coventry and the four boxes of catalogued deeds.
