“Reader, it hath not been usual here in England to make sale of Books by way of auction, or who will give most for them: But it having been practised in other countreys to the advantage both of buyers and sellers, it was therefore conceived (for the encouragement of Learning) to publish the sale of these Books this manner of way, and it is hoped that this will not be unacceptable to Schollers....” Mr. Alfred W. Pollard, in a very valuable article on English Book Sales, 1676-80 (_Bibliographica_, vol. i. p. 373), quotes an interesting letter from David Millington to Joseph Hill, an English Nonconformist minister in Holland, dated June 1697, and now preserved in the British Museum (Stowe MS., 709), in which the writer tenders to the divine his thanks for the “great service done to learning and learned men in your first advising and effectually setting on foot that admirable and universally approved way of selling librarys amongst us;” and distinctly states that it was Hill who “happily introduced the practice into England.” Mr. Pollard goes on to say that “Hill, who from 1673 to 1678, owing to his publication of a pamphlet which gave offence to the Dutch Government, was resident in England, must have advised the executors of Dr. Seaman, a theologian of principles not widely different from his own, to adopt this method of selling his friend’s library to the best advantage.” Seaman was the author of “A Vindication of the Judgement of the Reformed Churches, &c., concerning Ordination, &c.,” 1647, and the chief class of books in his library was what we might expect to find, viz., theological works that he required in his vocation. Some few books (such as the Eliot Bible of 1661-63, nineteen shillings) fetched small prices as compared with their present value, but Mr. Pollard says that “nine-tenths of the books sold for more than they would at the present day.” The library was a large one, and the lots numbered between five and six thousand, and the amount realised by the sale was a little over £700, which may be roughly estimated at about £3500 of our present money. The second auction sale (February 1676-67) was also carried out by Cooper, and consisted of the library of Thomas Kidner, Rector of Hitchin, in Hertfordshire, who died 31st August 1676. The library, like that of Dr. Seaman, consisted largely of theological works. It is evident from Cooper’s preface to this catalogue that Seaman’s sale had given considerable satisfaction, although the reference to an attempt to stifle this manner of sale shows that there were some opponents of the system.
