“The mercenary spirit must not be admitted to a share in the enjoyments of the book-hunter.... If [he] allows money-making, even for those he is to leave behind, to be combined with his pursuit, it loses its fresh relish, its exhilarating influence, and becomes the source of wretched cares and paltry anxieties. When money is the object, let a man speculate or become a miser.”...
This is quite true, but we must remember that, after all, increased price is only an outward manifestation of increased public estimation, and it is always satisfactory to know that our opinion has been accepted by the public. The real point seems to be that the collector should use his judgment in respect to price, and not trouble himself whether the market value of individual books goes up or down, for he may be sure that if he buys wisely, the ups and the downs will balance each other. If a fair-sized library is purchased with judgment and knowledge, it cannot fail to become a profitable investment, because good books increase in value by reason of their companionship. All worthless books should therefore be ruthlessly weeded out. For instance, a library of 1000 choice books would probably sell for less with 500 books of little value added to them than if these were ruthlessly eliminated.

But Mr. Lang did not think of a calculation, by which Mr. A. W. Pollard, in an interesting article on “English Booksales, 1676-86” (Bibliographica, vol. ii. p. 126), overthrew this view of the possibility of great gains. He writes—
