A photographer offered to a public library a fine collection of portraits of deceased citizens of the town. This was accepted. The photographer then proceeded to send out circulars in a way that rendered it very probable that he was simply using the library’s name to increase his business. A commercial firm, which had issued a good book on a subject connected with its business, offered to print for various libraries, at its own expense, a good list of works on this subject on condition that it should be allowed to advertise its own book on the last page. Submission of a proof revealed the fact that this advertisement was to be printed in precisely the same form and with the same kind of heading as information about the library given on the preceding page. The reader’s inference would have been that the matter on the last page was an official library note. Of the libraries approached, some accepted the offer without finding any fault with the feature just noted; others refused to have anything at all to do with the plan; still others accepted on condition that the last page should be so altered that the reader could see clearly that it contained advertising matter. A lecturer gained permission to distribute through a library complimentary tickets to a free lecture on an educational subject. When these arrived, the librarian discovered that the announcement of the free lecture was on the same folder with advertisements of a pay course. The free tickets were given out, but the advertisement was suppressed. Efforts of this kind are perhaps particularly noticeable in connection with the use of library assembly-rooms. There is no reason, of course, why libraries should not rent out these rooms in the same way as other public rooms, but it is usual to limit their use to educational purposes and generally to free public entertainments. Some efforts to circumvent rules of this kind are interesting. Application was made to a library for the use of an assembly-room for a free lecture on stenography. On cross-examination the lecturer admitted that he was a teacher of stenography who desired to form a class, and that at the close of his lecture he intended to make announcement of his courses, prices, etc. He was told that this must be done outside the library.
