Unfortunately the library cannot control the output of books, and must limit itself to selection. An experiment in such selection is now in progress in the St. Louis Public Library. The visitor to that library will find in its Open Shelf Room a section of shelving marked with the words "Books in large type." To this section are directed all readers who have found it difficult or painful to read the ordinary printed page but who do not desire to wear magnifying lenses. It has not been easy to fill these shelves, for books in large type are few, and hard to secure, despite the fact that artists, printers, and oculists have for years been discussing the proper size, form, and grouping of printed letters from their various standpoints. Perhaps it is time to urge a new view--that of the public librarian, anxious to please his clients and to present literature to them in that physical form which is most easily assimilable and least harmful.
Tired eyes belong, for the most part, to those who have worked them hardest; that is, to readers who have entered upon middle age or have already passed through it. At this age we become conscious that the eye is a delicate instrument--a fact which, however familiar to us in theory, has previously been regarded with aloofness. Now it comes home to us. The length of a sitting, the quality, quantity, and incidence of the light, and above all, the arrangement of the printed page, become matters of vital importance to us. A book with small print, or letters illegibly grouped, or of unrecognizable shapes, becomes as impossible to us as if it were printed in the Chinese character.
It is an unfortunate law of nature that injurious acts appear to us in their true light only after the harm is done. The burnt child dreads the fire after he has been burned--not before. So the fact that the middle-aged man cannot read small, or crooked, or badly grouped type means simply that the harmfulness of these things, which always existed for him, has cumulated throughout a long tale of years until it has obtruded itself upon him in the form of an inhibition. The books that are imperative for the tired eyes of middle age, are equally necessary for those of youth--did youth but know it. Curiously enough, we are accustomed to begin, in teaching the young to read, with very legible type. When the eyes grow stronger, we begin to maltreat them. So it is, also, with the digestive organs, which we first coddle with pap, then treat awhile with pork and cocktails, and then, perforce, entertain with pap of the second and final period. What correspond, in the field of vision, to pork and cocktails, are the vicious specimens of typography offered on all sides to readers--in books, pamphlets, magazines, and newspapers--typography that is slowly but surely ruining the eyesight of those that need it most.
