We have received The English Catalogue of Books, Vol. VII.,

1901-1905 (Publisher's Circular C ffice, ..£.3 13s. 6d. net), a catalogue with price, size, /cc., of "Books issued in the United Kingdom of Great Britain and Ireland" during the five years given above. The catalogue is double, giving both author and subject. It extends, we see, to twelve hundred and ten pages, while an appendix of more than a hundred pages gives lists of "Libraries," "Series," and the like in which standard books are republished. It would be highly interesting to know how many of these works, not less, we imagine, than ten thousand in number, could be profitably subjected to Mr. Henniker Heaton's summary process -of halving the price.
