In fact, the library idea itself is beginning to suffer a sort of restless change that is quite distinct from its orderly progress. The activities of the library are at present a good deal like those of the amoeba--stretching out a tentacle here, withdrawing one there; improvising a mouth and then turning it into a stomach; shifting and stretching about; somewhat vague and formless, yet instinct with life, appetite and caution, and vitalized with at least the germ and promise of intelligence. Such a state is an unpromising one for prophecy. Is this or that new development of activity the beginning of an orderly march in a straight line, or is it to be withdrawn or reversed to-morrow? Is our work with children to include much that now seems to belong to the kindergarten, the museum, and the art gallery? Are our travelling library departments to sell books in the future as well as lend them? Are we to deliver books free at our user’s homes? Are our Boards of Education to turn over to us the superintendence of all such work as deals with books and their use? Many questions like these would have been answered in the affirmative yesterday but in the negative to-day. I might be inclined to say “yes” to some of them now, when to-morrow would prove them out of the question. But there is one assertion that we can make boldly. Whatever the library has tried to do or to be, whether success or failure has attended it, it has never ceased to be a library--a keeper and purveyor of books. Whatever else it may undertake, we may be sure that this will continue to be its chief reason for existence, and that its other activities, if such there be, will grow out of this and group themselves around it. Is the library to grow into a bookstore? I do not know, but if so its commercial functions are likely to be subsidiary. Certain libraries have already added to their duties as free institutions the functions of pay-libraries, and the commercial feature has thus been introduced. It seems to be spreading, and it may prove an entering wedge for a system of actual sales to supplement that of paid loans. A powerful deterrent, however, will be the influence of the book-trade. Following the line of least resistance, the activity of the library as an aid to the ownership as well as the reading of books is perhaps more likely to manifest itself in advice than in actual trade. Some libraries are now making special effort to give their readers information about book-prices, and about places and methods of purchase; and it seems likely that this kind of aid, since it can arouse no opposition, will increase.
