Books may be used in three ways—for information, for recreation, for inspiration. There are some who feel inclined to rely implicitly on the information that is to be found in books—to believe that a book can not lie. This is an unfortunate state of mind. The word of an author set down in print is worth no more than when he gives it to us in spoken language—no more and no less. There was, to be sure, a time when the printed word implied at least care and thoughtfulness. It is still true that the book implies somewhat more of this than the newspaper, but the difference between the two is becoming unfortunately less. Now a wrong record, if it purports to be a record of facts, is worse than none at all. The man who desires to know the distance between two towns in Texas and is unable to find it in any book of reference may obtain it at the cost of some time and trouble; but if he finds it wrongly recorded, he accepts the result and goes away believing a lie. If we are to use books for information, therefore, it is of the utmost consequence that we know whether the information is correct or not. A general critical evaluation of all literature, even on this score alone, without going into the question of literary merit, is probably beyond the possibilities, although it has been seriously proposed. Some partial lists we have, and a few lists of those lists, so that we may know where to get at them. There are many books about books, especially in certain departments of history, technology, or art, but no one place to which a man may go, before he begins to read his book, to find out whether he may believe what he reads in it. This is a serious lack, especially as there is more than one point of view. Books that are of high excellence as literature may not be at all accurate. How shall the boy who hears enthusiastic praise of Prescott’s histories and who is spellbound when he reads them know that the results of recent investigation prove that those histories give a totally incorrect idea of Mexico and Peru? How is the future reader of Dr. Cook’s interesting account of the ascent of Mount McKinley to know that it has been discredited? And how is he to know whether other interesting and well-written histories and books of travel have not been similarly proved inaccurate? At present, there is no way except to go to one who knows the literature of the subject, or to read as many other books on the subject as can be obtained, weighing one against the other and coming to one’s own conclusions. Possibly the public library may be able to help. Mr. Charles F. Lummis of the Los Angeles library advocates labelling books with what he calls “Poison Labels” to warn the reader when they are inaccurate or untrustworthy. Most librarians have hesitated a little to take so radical a step as this, not so much from unwillingness to assume the duty of warning the public, as from a feeling that they were not competent to undertake the critical evaluation of the whole of the literature of special subjects. The librarian may know that this or that book is out of date or not to be depended on, but there are others about which he is not certain or regarding which he must rely on what others tell him. And he knows that expert testimony is notoriously one-sided. It is this fear of acting as an advocate instead of as a judge that has generally deterred the librarian from labelling his books with notes of advice or warning.

There is, however, no reason why the librarian should take sides in the matter. He may simply point out to the reader that there are other books on the same subject, written from different points of view, and he may direct attention to these, letting the reader draw his own conclusions. There is probability that the public library in the future will furnish information and guidance of this kind about books, more than it has done in the past.

And here it may be noted in passing that the library is coming out of its shell. It no longer holds itself aloof, taking good care of its books and taking little care of the public that uses them. It is coming to realize that the man and the book are complementary, that neither is much without the other, and that to bring them together is its duty. It realizes also that a book is valuable, not because it is so much paper and ink and thread and leather, but because it records and preserves somebody’s ideas. It is the projection of a human mind across space and across time and where it touches another human mind those minds have come into contact just as truly and with as valuable results as if the bodies that held them stood face to face in actual converse. This is the miracle of written speech—a miracle renewed daily in millions of places with millions of readers.

We have, in the modern library, the very best way of perpetuating such relations as this and of ensuring that such as are preserved shall be worth preserving. When the ancients desired to make an idea carry as far as possible, they saw to the toughness and strength of the material object constituting the record; they cut it in stone or cast it in metal, forgetting that all matter is in a state of continual flux and change; it is the idea only that endures. Stone and metal will both one day pass away and unless some one sees fit to copy the inscription on a fresh block or tablet, the record will be lost. It is, then, only by continual renewal of its material basis that a record in written language can be made to last, and there is no reason why this renewal should not take place every few years, as well as every few centuries. There is even an advantage in frequent renewal; for this ensures that the value of the record shall be more frequently passed upon and prevents the preservation of records that are not worth keeping. This preservation by frequent renewal is just what is taking place with books; we make them of perishable materials; if we want to keep them, we reprint them; otherwise they decay and are forgotten.

We should not forget that by this plan the reader is usually made the judge of whether a book is worth keeping. Why do we preserve by continual reprinting Shakespeare and Scott and Tennyson and Hawthorne? The reprinting is done by publishers as a money-making scheme. It is profitable to them because there is a demand for those authors. If we cease to care for them and prefer unworthy writers, Shakespeare and Scott will decay and be forgotten and the unworthy ones will be preserved. Thus a great responsibility is thrown upon readers; so far they have judged pretty well.

Just now, however, we are confining ourselves to the use of books for information; and here there is less preservation than elsewhere. Especially in science, statements and facts quickly become out of date; here it is not the old but the new that we want—the new based on the accurate and enduring part of the old.

Before we leave this part of the subject it may be noted that many persons have no idea of the kinds of information that may be obtained from books. Even those who would unhesitatingly seek a book for data in history, art, or mathematics would not think of going to books for facts on plumbing, weaving, or shoe-making, for methods of shop-window decoration or of display-advertising, for special forms of bookkeeping suitable for factories or for stock-farms—for a host of facts relating to trades, occupations, and business in general. Yet there are books about all these things—not books perhaps to read for an idle hour, but books full of meat for them who want just this kind of food. If Book-taught Bilkins fails, after trying to utilize what such books have taught him, it is doubtless because he has previously failed to realize that books plus experience, or, to put it differently, the recorded experience of others plus our own is better than either could be separately. And the same is true of information that calls for no physical action to supplement it. Books plus thought—the thoughts of others plus our own—are more effective in combination than either could be by itself. Reading should provoke thought; thought should suggest more reading, and so on, until others’ thoughts and our own have become so completely amalgamated that they are our personal intellectual possessions.

But we may not read for information at all—recreation may be what we are after. Do not misunderstand me. Many persons have an idea that if one reads to amuse himself he must necessarily read novels. I think most highly of good novels. Narrative is a popular form of literary expression; it is used by those who wish to instruct as well as to amuse. One may obtain plenty of information from novels—often in a form nowhere else available. If we want exact statement, statistical or otherwise, we do not go to fiction for it; but if we wish to obtain what is often more important—accurate and lasting general impressions of history, society, or geography, the novel is often the only place where these may be had. Likewise, one may amuse himself with history, travel, science, or art—even with mathematics. The last is rarely written primarily to amuse, although we have such a title as “Mathematical recreations,” but there are plenty of non-fiction books written for entertainment and one may read for entertainment any book whatever. The result depends not so much on the book or its contents as on the reader.

Recreation is now recognized as an essential part of education. And just as physical recreation consists largely in the same muscular movements that constitute work, only in different combinations and with different ends in view, so mental recreation consists of intellectual exercise with a similar variation of combinations and aims.

Somebody says that “play is work that you don’t have to do”. So reading for amusement may closely resemble study—the only difference is that it is purely voluntary. Here again, however, the written language is only an intermediary; we have as before, the contact of two minds—only here it is often the lighter contact of good-fellowship. And one who reads always for such recreation is thus like the man who is always bandying trivialities, story-telling, and jesting—an excellent, even a necessary, way of passing part of one’s time, but a mistaken way of employing all of it.
