A small and select library will naturally average a much higher amount than a large library, in which many commonplace books must be included. These averages, however, will not help us very much to understand the relative value of libraries.
For instance, at the Sunderland sale some lots sold for enormous sums, while a large number fell for a few shillings; but at the Hamilton Palace sales (William Beckford and the Duke of Hamilton) nearly every lot was of value, and although individual lots did not reach the sums realised at the Sunderland sale, the total was much larger. As an instance of what is meant, we may quote from the notice of the Ashburnham sale in the Times—
“The 1683 lots realised a grand total of £30,151, 10s., which works out at an average of as nearly as possible £18 per lot. Hitherto the highest average was obtained by the disposal in 1884 of the Syston Park library, where 2110 lots brought £28,000, or £13, 5s. per lot, the next highest average being that of the Seillière library, sold in 1887, 1140 lots realising £14,944, or about £13, 2s. per lot. It is scarcely fair, however, to compare the Ashburnham collection with either of these two libraries, as the Seillière was admittedly only the choice portion of the assemblage of the baron, whilst nearly every lot in the Syston Park library was of importance. Eliminating from the Ashburnham collection the hundreds of lots which realised less than £1 each, the average would be nearer £40 than £18.”
This is all very well in its way, but one lot fetched £4000, and such an amount would demoralise any average. Let us therefore see what are the particular points worthy of notice in the sums making up this large total of £30,151. We find that five lots realised £1000 and over each, and including these five lots, forty-two were over £100 each. Now the total for these forty-two lots is £20,348, which, if we deduct from the grand total, leaves 1641 lots for £9803, bringing our average down considerably.
This is not perhaps a quite fair system of striking an average, but it shows better how the prices of the books are distributed.
CHAPTER VIII
PRICES OF EARLY PRINTED BOOKS
It is impossible in the following chapters to do more than select some of the chief classes of valuable books in order to indicate the changes that have taken place in the prices. It will be noticed that the great enhancement of prices which is so marked a feature of the present age commenced about the beginning of the present century.
Bibliomania can scarcely be said to have existed in the seventeenth century, but it commenced in the middle of the next century, when the Mead library was sold. Still it attracted little attention until the sale of the Roxburghe library in 1812, when it had become a power. In the middle of the present century there was a dull time, but during the last quarter the succession of sales realising one, two, and three thousand pounds have been continuous, with occasional sales realising much larger amounts. Great changes have occurred at different times in the taste of collectors for certain classes of books.
