"THE ENGLISH CATALOGUE OF BOOKS."

[To ma EDITOR or THE " SPECTATOR."] Pie,—In your very kind notice of our annual volume for 1918 of The English Catalogue of Books you mention that you think far more than five hundred and sixty-eight pamphlets were published last year. The international rule in this rather difficult matter is to consider unbound works of less than forty-eight pages as pamphlets; and all with more pages as books. We follow this plan as closely as we can, and include everything of which we can get particulars. Of course, it would make the Catalogue of Books too bulky and expensive if we included every tract or leaflet and similar ephemeral printings.
