Hitherto, the public librarian has been more concerned with the minds and the morals of his clientele than with that physical organism without which neither mind nor morals would be of much use. It would be easy to pick out on the shelves of almost any public library books that are a physiological scandal, printed in type that it is an outrage to place before any self-respecting reader. I have seen copies of "Tom Jones" that I should be willing to burn, as did a puritanical British library-board of newspaper notoriety. My reasons, however, would be typographic, not moral, and I might want to add a few copies of "The Pilgrim's Progress" and "The Saint's Everlasting Rest," without prejudice to the authors' share in those works, which I admire and respect. Perhaps it is too much to ask for complete typographical expurgation of our libraries. But, at least, readers with tired eyes who do not yet wear, or care to wear, corrective lenses, should be able to find, somewhere on the shelves, a collection of works in relatively harmless print--large and black, clear in outline, simple and distinctive in form, properly grouped and spaced.
The various attempts to standardize type-sizes and to adopt a suitable notation for them have been limited hitherto to the sizes of the type-body and bear only indirectly on the size of the actual letter. More or less arbitrary names--such as minion, bourgeois, brevier, and nonpareil,--were formerly used; but what is called the point-system is now practically universal, although its unit, the "point," is not everywhere the same. Roughly speaking, a point is one-seventy-second of an inch, so that in three-point type, for example, the thickness of the type-body, from the top to the bottom of the letter on its face, is one-twenty-fourth of an inch. But on this type-body the face may be large or small--although of course, it cannot be larger than the body,--and the size of the letters called by precisely the same name in the point notation may vary within pretty wide limits. There is no accepted notation for the size of the letters themselves, and this fact tells, more eloquently than words, that the present sizes of type are standardized and defined for compositors only, not for readers, and still less for scientific students of the effect upon the readers' eyes of different arrangements of the printed page.
