knowledge of psychology may be a great aid in library work. To be successful, the compiler of a book list should thoughtfully consider whom he hopes to reach by it and then take measures to see that it reaches them. Advertise your list, and do not for a moment think that great literature, because it is great, needs no advertising. If your local paper will say that the library is distributing a fine list on the immortal Greek tragedies, far more people will be interested in that list than if you merely hand it out at your delivery desk. The most encouraging thought in regard to the promoting of the reading of the best books by means of lists is the broad field from which the books can be selected. The true book-lover in library work often feels like Tantalus--seeing all the time so much he would like to read and cannot. And so he turns with avidity to preparing for more fortunate mortals lists, not only of the things he has read and loved, but of the things he would love to read. Poetry, drama, essays, biography, letters, travel--here is a world from which to choose. Supplementing the lists and adding to their attractiveness are collections of the books themselves. In large libraries most people are more or less at sea. Who has not seen them wandering aimless and bewildered from shelf to shelf, and who has not noted the relief with which they turn to almost any small selection of books. Many libraries have kept statistics showing the circulation of books placed on special shelves, and it is invariably found that it is much higher than that of the books kept in their regular places. This has passed the experimental stage. Today we know that we can in this way increase the use of any books we select. There are just as good books in the stack, but they will not be read to anything like the same extent. A library has in its delivery room certain shelves on which appear all the new books that are bought, regardless of class. The circulation from these shelves is notably large. After a varying length of time these books are sent to the regular shelves. Immediately the use of them decreases. Books that were read almost continuously while they were on the special shelves only go out occasionally. But take them back to one of the small miscellaneous collections in the delivery room and they immediately begin to circulate again. The merchants learned long ago that people buy what they see, and so in all the stores a large amount of stock is on the counters for inspection. Librarians have learned that people also read what they see. In both cases, however, the methods adopted to secure patrons are influenced by the natural limitation as to the amount that can profitably be seen. The experienced clerk does not show the prospective buyer too many different kinds of cloth, lest he should become confused, be unable to decide, and refrain from buying. So with the reader. He can select something satisfactory from a single case of books, when row after row
