This valuable collection was purchased after the death of Edward Harley, second Earl of Oxford, by T. Osborne, the well known bookseller, for £30,000. The catalogue made by T. Oldys, with a preface by Dr. S. Johnson, was issued in parts; the first two volumes in 1743, and two more in 1744. The last volume is not, properly, a part of the work, though issued under the same name. The books were not sold by auction, and the prices were not affixed, as is usual with booksellers. For a valuable article on this catalogue (containing 360,000 volumes), see _Notes and Queries_. HARPEL (O. H.) Harpel's Typograph, or Book of Specimens.
