least three million volumes have been issued, and these may fairly be taken to represent thirty million readers.

In accepting the responsibility of so large an undertaking, Messrs. Bell and Daldy desire to carry on the projects of Mr. Bohn with the same spirit and energy which have influenced him, and they are happy to announce they will have the advantage of his bibliographical knowledge and large experience.

In addition to the Libraries of Mr. Bohn, this Catalogue comprises the various Collections published by Messrs. Bell and Daldy during the last nine years, and now in progress.

These Libraries and Collections together afford a choice from about 800 volumes on general literature and education.

To assist purchasers in making their selections a classified index is attached, by which they will be guided to the subjects of the books.

Messrs. Bell and Daldy venture to add, that the Aldine Poets, Aldine Series, British Worthies, Elzevir Series, and Pocket Volumes, are specially prepared for the lovers of choice books, and are specimens of careful editing combined with the most finished workmanship in all external features. They believe that they are not surpassed in these respects by any similar productions of the present day.

Many of the above works are adapted for prizes and presents; and they may be had through any bookseller, bound in a suitable style, by giving a short notice.
