Sometimes we have cases resembling those of the applicants for charitable aid from various sources. Members of the public entitled to library service, the amount of which has been limited by the rules to ensure proper distribution and to prevent monopoly, manage to get two or three times as much as they should get, by applying to different departments, or to the same department under different names. There has been much removal of restrictions of late, in libraries, with the intent to give fuller and freer service to the public. There should be no restriction that interferes with such service. But many restrictions are intended merely to check those whose tendency is to hamper service; and removal of these will evidently injure the public, not benefit it. Traffic regulations are a great bother, but their removal would not be in the public interest. Neither would the removal of necessary regulation of library traffic--the free distribution of books through the appointed public agencies. I sympathize with our modern desire to let Mr. A have as many books as he wants and to keep them as long as he wants; but this sympathy changes to indignation when Mr. A proves to be a library hog, taking advantage of his privileges simply to keep away from Mr. B and Miss C the books that they want. Now and again we find a reader who understands increase of library privileges to mean taking a book away from someone else and giving it to _him_. There could be no more flagrant example of the double sin of duplication and omission--giving A more than he can use and thereby depriving B of what he needs. The expenditure of time is a domain in which our two sins become especially noticeable. If one has plenty of money he may waste a good deal without serious effects; but waste of time is different. The total extent of time is doubtless infinite, but not its extent as available to the individual. He has only his three-score years and ten, and astronomical happenings have chopped this up for him into years, months, weeks and days, any one of which is largely a repetition of those that have gone before. So many of our duties, for instance, are daily that the average man has only a few hours out of the twenty-four to deal with emergency work, “hurry calls” and all sorts of exceptional demands on his time. If he gives ten minutes to something that requires but five, he must often neglect a duty, and this constitutes duplication and omission of time, to be remedied by taking the unnecessary five minutes from one task and bestowing it on another. Here again, however, our algebraic addition is simple only on paper. We are hindered not only by our own propensity to waste time but by those whose own is of no value and who therefore insist on wasting ours for us.
