The department was further enriched, in 1762, by a donation from George III. of a collection of pamphlets and periodicals published in the convulsive interval between the years 1640 and 1660. Chiefly illustrative of the civil wars in the time of Charles I., they were collected by an eminent bookseller, George Thomason; the whole comprises upwards of 30,000 articles, bound in about 2,000 volumes.

It is impossible to enumerate in detail all the additions which have been since made by gift or purchase. Dr. Thomas Birch’s library, bequeathed in 1766, is rich in biography; two collections of books on musical science were also presented—one by Sir John Hawkins, in 1778, and the other by Dr. Charles Burney.

In 1780, 900 volumes of old English plays were given to the Museum by Garrick. In 1786, numerous classics from the library of Thomas Tyrwhitt, and a collection of ceremonials, processions, and heraldry from Mrs. Sophia Sarah Banks was added. These gifts were supplemented in 1818, two years later, by the library of Sir Joseph Banks, consisting of about 16,000 volumes, particularly rich in scientific journals, transactions of societies, and books on natural history, but which were not actually transferred to the Museum till 1827.

A collection of Italian history and topography from Sir Richard Colt-Hoare, Bart., was presented in 1825. This gentleman printed only twelve copies of the catalogue of his books, and wrote on the fly-leaf of the copy which accompanied the presentation, “Anxious to follow the liberal example of our gracious monarch, George IV.; of Sir George Beaumont, Bart., of Richard Payne-Knight, Esq. (though in a very humble degree), I do give unto the British Museum THIS my collection of topography, made during a residence of five years abroad, and hoping that the more modern publications may be added to it hereafter, A.D. 1825. Richard Colt-Hoare. This catalogue contains 1,733 articles.”

The valuable library of the Rev. Clayton Mordaunt Cracherode, consisting of 4,500 volumes, came into the possession of the Museum in 1799; and lastly, in 1835, Major-General Hardwicke bequeathed to the Trustees the deficient works on natural history which formed part of his library, and which caused an accession of 300 volumes.

Parliament also evinced its interest in the library, and gave instructions for the following purchases:—

Mr. Francis Hargrave, an eminent barrister, had formed an important collection of law books, which was purchased in 1813 for £8,000, having been valued by a bookseller at £2,247. 8s.

Dr. Burney’s library was likewise purchased in 1818, and was estimated at the value of 9,000 guineas. It contained a remarkable collection of Greek classics, besides 700 volumes of newspapers, &c., &c.

In 1769 a sum of £7,000 was paid for Major Edwards’ library, and in 1804 the sum of £150 was applied to the purchase of a collection of Bibles belonging to Mr. Combe.
