Every one commits errors, but the wise man is he who learns by his mistakes, and applies the remedy. The best remedy (as I said in the case of memory in another chapter,) is to cultivate a habit of trained attention in whatever we do. Yet many people (and I am afraid we must say most people) go on through life, making the same blunders, and repeating them. It appears as if the habit of inaccuracy were innate in the human race, and only to be reformed by the utmost painstaking, and even with the aid of that, only by a few. I have had to observe and correct such numberless errors in the work of well-educated, adult, and otherwise accomplished persons, as filled me with despair. Yet there is no more doubt of the improvability of the average mind, however inaccurate at the start, than of the power of the will to correct other bad habits into which people unconsciously fall.

One of the requisites of a successful librarian is a faculty of order and system, applied throughout all the details of library administration. Without these, the work will be performed in a hap-hazard, slovenly manner, and the library itself will tend to become a chaos. Bear in mind the great extent and variety of the objects which come under the care of the librarian, all of which are to be classified and reduced to order. These include not only books upon every earthly subject (and very many upon unearthly ones) but a possibly wide range of newspapers and periodicals, a great mass of miscellaneous pamphlets, sometimes of maps and charts, of manuscripts and broadsides, and frequently collections of engravings, photographs, and other pictures, all of which come in to form a part of most libraries. This great complexity of material, too, exhibits only the physical aspect of the librarian's labors. There are, besides, the preparation, arrangement and continuation of the catalogue, in its three or more forms, the charging and crediting of the books in circulation, the searching of many book lists for purchases, the library bills and accounts, the supervision and revision of the work of assistants, the library correspondence, often requiring wide researches to answer inquiries, the continual aid to readers, and a multitude of minor objects of attention quite too numerous to name. Is it any over-statement of the case to say that the librarian who has to organize and provide for all this physical and intellectual labor, should be systematic and orderly in a high degree?

That portion of his responsible task which pertains to the arrangement and classification of books has been elsewhere treated. But there is required in addition, a faculty of arranging his time, so as to meet seasonably the multifarious drafts upon it. He should early learn not only the supreme value of moments, but how to make all the library hours fruitful of results. To this end the time should be apportioned with careful reference to each department of library service. One hour may be set for revising one kind of work of assistants; another for a different one; another for perusing sale catalogues, and marking desiderata to be looked up in the library catalogue; another for researches in aid of readers or correspondents; still another for answering letters on the many subjects about which librarians are constantly addressed; and still another for a survey of all the varied interests of the library and its frequenters, to see what features of the service need strengthening, what improvements can be made, what errors corrected, and how its general usefulness can be increased. So to apportion one's time as to get out of the day (which is all too short for what is to be done in it) the utmost of accomplishment is a problem requiring much skill, as well as the ability to profit by experience. One has always to be subject to interruptions—and these must be allowed for, and in some way made up for. Remember, when you have lost valuable time with some visitor whose claims to your attention are paramount, that when to-morrow comes one should take up early the arrears of work postponed, and make progress with them, even though unable to finish them.

Another suggestion; proper system in the management and control of one's time demands that none of it be absorbed by trifles or triflers; and so every librarian must indispensably know how to get rid of bores. One may almost always manage to effect this without giving offense, and at the same time without wasting any time upon them, which is the one thing needful. The bore is commonly one who, having little or nothing to do, inflicts himself upon the busy persons of his acquaintance, and especially upon the ones whom he credits with knowing the most—to wit, the librarians. Receive him courteously, but keep on steadily at the work you are doing when he enters. If you are skilful, you can easily do two things at once, for example, answer your idler friend or your bore, and revise title-cards, or mark a catalogue, or collate a book, or look up a quotation, or write a letter, at the same time. Never lose your good humor, never say that your time is valuable, or that you are very busy; never hint at his going away; but never quit your work, answer questions cheerfully, and keep on, allowing nothing to take your eyes off your business. By and by he will take the hint, if not wholly pachydermatous, and go away of his own accord. By pursuing this course I have saved infinite time, and got rid of infinite bores, by one and the same process.

The faculty of organizing one's work is essential, in order to efficiency and accomplishment. If you do not have a plan and adhere to it, if you let this, that, and the other person interrupt you with trifling gossip, or unnecessary requests, you will never get ahead of your work; on the contrary, your work will always get ahead of you. The same result will follow if you interrupt yourself, by yielding to the temptation of reading just a page or a paragraph of something that attracts your eye while at work. This dissipation of time, to say nothing of its unfair appropriation of what belongs to the library, defeats the prompt accomplishment of the work in hand, and fosters the evil habit of scattering your forces, in idleness and procrastination.

It ought not to be needful to urge habits of neatness and the love of order upon candidates for places in libraries. How much a neat and carefully arranged shelf of books appeals to one's taste, I need not say, nor urge the point how much an orderly and neatly kept room, or desk, or table adds to one's comfort. The librarian who has the proper spirit of his calling should take pains to make the whole library look neat and attractive, to have a place for everything, and everything in its place. This, with adequate space existing, will be found easier than to have the books and other material scattered about in confusion, thus requiring much more time to find them when wanted. A slovenly-kept library is certain to provoke public criticism, and this always tells to the disadvantage of the librarian; while a neatly kept, carefully arranged collection of books is not only pleasing to the eye, but elicits favorable judgment from all visitors.

Among the qualities that should enter into the composition of a successful librarian must be reckoned an inexhaustible patience. He will be sorely tried in his endeavors to satisfy his own ideals, and sometimes still more sorely in his efforts to satisfy the public. Against the mistakes and short-comings of assistants, the ignorance of many readers, and the unreasonable expectations of others, the hamperings of library authorities, and the frequently unfounded criticisms of the press, he should arm himself with a patience and equanimity that are unfailing. When he knows he is right, he should never be disturbed at complaint, nor suffer a too sensitive mood to ruffle his feelings. When there is any foundation for censure, however slight, he should learn by it and apply the remedy. The many and varied characters who come within the comprehensive sphere of the librarian necessarily include people of all tempers and dispositions, as well as of every degree of culture. To be gracious and courteous to all is his interest as well as his duty. With the ignorant he will often have to exercise a vast amount of patience, but he should never betray a supercilious air, as though looking down upon them from the height of his own superior intelligence. To be always amiable toward inferiors, superiors, and equals, is to conciliate the regard of all. Courtesy costs so little, and makes so large a return in proportion to the investment, that it is surprising not to find it universal. Yet it is so far from being so that we hear people praising one whose manners are always affable, as if he were deserving of special credit for it, as an exception to the general rule. It is frequently observed that a person of brusque address or crusty speech begets crustiness in others. There are subtle currents of feeling in human intercourse, not easy to define, but none the less potent in effect. A person of marked suavity of speech and bearing radiates about him an atmosphere of good humor, which insensibly influences the manners and the speech of others.

There will often come into a public library a man whose whole manner is aggressive and over-bearing, who acts and talks as if he had a right to the whole place, including the librarian. No doubt, being a citizen, he has every right, except the right to violate the rules—or to make himself disagreeable. The way to meet him is to be neither aggressive, nor submissive and deferential, but with a cool and pleasant courtesy, ignoring any idea of unpleasant feeling on your part. You will thus at least teach a lesson in good manners, which may or may not be learned, according to circumstances and the hopeful or hopeless character of the pupil.

Closely allied to the virtue of patience, is that of unfailing tact. This will be found an important adjunct in the administration of a public library. How to meet the innumerable inquiries made of him with just the proper answer, saying neither too much, nor too little, to be civil to all, without needless multiplication of words, this requires one to hold his faculties well in hand, never to forget himself, and to show that no demand whatever can vex or fluster him. The librarian should know how, or learn how to adapt himself to all readers, and how to aid their researches without devoting much time to each. This requires a fine quality of tact, of adapting one's self quickly to the varied circumstances of the case in hand. One who has it well developed will go through the manifold labors and interviews and annoyances of the day without friction, while one who is without tact will be worried and fretted until life seems to him a burden.

Need I mention, after all that has been said of the exacting labors that continually wait upon the librarian, that he should be possessed both of energy and untiring industry? By the very nature of the calling to which he is dedicated, he is pledged to earnest and thorough work in it. He cannot afford to be a trifler or a loiterer on the way, but must push on continually. He should find time for play, it is true, and for reading for his own recreation and instruction, but that time should be out of library hours. And a vigilant and determined economy of time in library hours will be found a prime necessity. I have dwelt elsewhere upon the importance of choosing the shortest methods in every piece of work to be accomplished. Equally important is it to cultivate economy of speech, or the habit of condensing instructions to assistants, and answers to inquiries into the fewest words. A library should never be a circumlocution office. The faculty of condensed expression, though somewhat rare, can be cultivated.
