Many public libraries have wisely supplemented their own lecture schemes by co-operating with University Extension. Even where the library has not been able to offer a lecture room on the premises, such co-operation may be very valuable, and a reciprocal advantage to all concerned. The library can provide books for the students, issuing reading lists which have been drawn up in consultation with the lecturers; useful exhibitions, also, can be organized, from the library’s own stores or from other sources. The tutorial classes organized by the Workers’ Educational Association have been aided effectively by such co-operation, which always reacts beneficially, in more ways than meet the eye, on the libraries themselves. When there is intimate association between libraries and technical colleges, polytechnics, and the like, half at least of the real work will be done in the library or through the books supplied by the library. Nor is it only the urban libraries that are able to assert their true place in adult education thus; several of the new rural repositories are working hand in hand with the Workers’ Educational Association and its tutorial classes, which have not failed on their part to utilize machinery so apt to its purposes. Besides the ordinary stock of miscellaneous books for the general reader, the wise rural librarian lays in a good selection of the works required by reading circles and tutorial classes, if necessary duplicating until there are enough copies for all demands. But for this special call upon his resources, he would rely upon the Central Library for Students to meet the requirements in works of this class.
