After Phillipps died in 1872, the probate valuation, made by
Edward Bond of the British Museum, of his manuscripts was £74,779 17s 0d. His success as a collector owed something to the dispersal of the monastic libraries following the
French Revolution and the relative cheapness of a large amount of vellum material, in particular English legal documents, many of which owe their survival to Phillipps. He was an assiduous cataloguer who established the Middle Hill Press (Typis Medio-Montanis) in 1822 not only to record his book holdings but also to publish his findings in English
topography and
genealogy. The press was housed in
Broadway Tower, a
folly completed on Broadway Hill, Worcestershire, in 1798. During his lifetime, Phillipps attempted to turn over his collection to the British nation and corresponded with the then-
Chancellor of the Exchequer Disraeli so that it should be acquired for the
British Museum. Negotiations proved unsuccessful and, ultimately, the dispersal of his collection took over 100 years. Phillipps's will stipulated that his books should remain intact at Thirlestaine House, that no bookseller or stranger should rearrange them and that no
Roman Catholic, especially his son-in-law James Halliwell, should be permitted to view them. In 1885, the
Court of Chancery declared this too restrictive and thus made possible the sale of the library which Phillipps's grandson, Thomas FitzRoy Fenwick, supervised for the next fifty years. Significant portions of the European material were sold to the national collections on the continent including the
Royal Library, Berlin, the
Royal Library of Belgium, and the Provincial Archives (
:nl:Gemeentearchief) in
Utrecht as well as the sale of outstanding individual items to the
J. Pierpont Morgan and
Henry E. Huntington libraries. By 1946, what was known as the "residue" was sold to London booksellers Phillip and
Lionel Robinson for £100,000, though this part of the collection was uncatalogued and unexamined. The Robinsons endeavoured to sell these books through their own published catalogues and a number of
Sotheby's sales. The final portion of the collection was sold by
Christie's on 7 June 2006, lots 18–38. A five-volume history of the collection and its dispersal,
Phillipps Studies, by A. N. L. Munby was published between 1951 and 1960. ==Family==
