Luck may not only be “in” but “of” the library. The whole institution may be in the lucky or unlucky class. I think you have known both kinds. The former seem to prosper, to do good work and to win golden opinions by the very fact of their existence. The latter have small appropriations, a poor standing in the community, and are finally destroyed by fire. Now personal ill-luck is and remains personal, but the ill-luck of an institution may be of various kinds. It may reside in a person or persons, or in a system, or in a building--or in all three. If the Jonestown Public Library is unlucky, the ill-luck may be that of its librarian, or of his staff, or he may be operating an unlucky system, or his building may be unlucky. I am an especial believer in unlucky buildings. Some there are in which it appears to be as impossible to run a successful library as it would be to grow vegetables in an ash-bin. Sometimes one can pick out the trouble with half an eye, although the same degree of astuteness seems to have been beyond the architect, or the board, or the librarian who co-operated to produce it. But in many cases we know the trouble only by its fruits; its roots are hidden, and the best we can do is to recognize that the library’s ill-luck comes from an unlucky building, and leave it at that. There are so many sources of this kind of general library ill-luck, that it is a wonder we do not see more unlucky libraries. There are not so very many lucky ones either, except so far as this proceeds from the possession of a staff whose members are individually lucky. The statistician knows that the way to eliminate chance is to multiply instances. The insurance actuary does not know when you will die, but he knows that of a million men of your age, very nearly so many will die within the next year. It is because he deals with a large number of cases that he can put his system on a business footing. There may be only one white ball in a bushel of black ones; you might conceivably draw that white ball at the first trial, but if you did you would properly refer to it as “luck”. If, however, you could multiply the number of trials, you would bring up the white ball sooner or later. There may be only one good way of accomplishing a result among thousands of bad ones. If you should hit on the right one at the first trial you would be “lucky”, but, luck or no luck, you will get it if you keep on long enough. Patience is always a winner in the long run.
