5. _Matter of cost._--This should be carefully considered. I hold it to be little short of criminal to recommend high priced books for libraries of limited means. By high priced books I mean those costing over $5 a volume. This of course does not apply to reference books. And yet in one annual list such books constantly appear, as not only suggestions but, considering the source, as recommendations or even commands. I am thankful the Wisconsin Library Commission has taken up this work systematically and is doing all it can to discourage such foolish waste of money. The worst example is the "Encyclopædia Britannica" now from 25 to 10 years behind the times and never a satisfactory book of reference at its best. Take De Bry's "Mycetazoa," it stands on the shelves of dozens of libraries, leaves uncut, totally unused, each copy meaning at least four dollars wasted money. These are only given as an example--there might be hundreds of them. There are scores of books now published and more coming out every day on various questions of philosophy, sociology, science, art and particularly literature and history priced from $1 to $2.50 which are far superior for practical purposes to the heavy weight monographs at $5 a volume and upwards. You thus get two or three books on the same subject for the money, and in a small library this is a vital question. The money must bring in the largest possible number of good books. BOOK REVIEWS, BOOK LISTS, AND ARTICLES ON CHILDREN'S READING: ARE THEY OF PRACTICAL VALUE TO THE CHILDREN'S LIBRARIAN? BY CAROLINE M. HEWINS, _Hartford (Ct.) Public Library_. A children's librarian has three sources of reliance in the choice or purchase of books. They are: 1, Book reviews in current or earlier periodicals; 2, Lists, graded or ungraded, for libraries; 3, Articles on children's reading in books or periodicals. 1. The children's librarian, or any librarian, who orders children's books from reviews often finds the books entirely different from what the description has led her to suppose. Even if there is no positive untruth in a notice, it is often misleading from the lack of a standard of comparison with the best books for children.
