This book contains the prayers and hymns used in the Chapels Royal during the reign of George III. It was formerly in the Chapel Royal at St James's Palace. The Royal Library holds several examples of books bound for use in the Chapels Royal and many bear the same binding tool. This example was selected by Olwen Hedley in the 1960s as a fine example of bookbinding in the Royal Library at Windsor Castle. Hedley’s ‘Additional Bookbindings’ serve as a supplement to the catalogue of fine bindings compiled in 1893 by the Royal Librarian Richard Rivington Holmes.
