At Liverpool, where library, museum, and art gallery are in the same suite of buildings, and under one general committee, sections of which are detailed to supervise the several departments, there is an example of intimate correlation on the largest scale. Here, in the Picton Theatre under the central library and in the lecture halls attached to the branches, free courses of lectures have been carried on ever since 1865, averaging now some two hundred yearly, with an aggregate annual attendance of nearly 200,000. At Bootle, Salford, Warrington, Wigan, Cardiff, Wallasey, Bristol, Derby, Norwich, Maidstone, Leek, and other places, mostly in the midlands, and at Islington, Croydon, Woolwich, Walthamstow, Camberwell, Kingston, Chelsea, Hampstead, Fulham, Hornsey, Bromley, and other public libraries in the London area, winter series of public lectures were in full swing in the years before the war, and in many cases have not been discontinued or have since been revived. A good proportion of these libraries are of the old composite type, complete with museum and art gallery; others are tending to become such. At Nottingham, where the public library is in partnership, as it were, with the University College next door, among various extension efforts the half-hour talks on books and reading have for several decades been a popular mode of stimulating taste and self-education, both in adults and in children, and have been widely imitated. The Manchester Public Library was the pioneer in this provision of lectures bearing directly on the uses of libraries and the best methods of reading and private study.
