Private-subscription libraries functioned in much the same manner as commercial subscription libraries, though they varied in many important ways. One of the most popular versions of the private-subscription library was the "gentlemen only" library. The gentlemen's subscription libraries, sometimes known as proprietary libraries, were nearly all organized on a common pattern. Membership was restricted to the proprietors or shareholders, and ranged from a dozen or two to between four and five hundred. The entrance fee, i.e. the purchase price of a share, was in early days usually a guinea, but rose sharply as the century advanced, often reaching four or five guineas during the French wars; the annual subscription, during the same period, rose from about six shillings to ten shillings or more. The book-stock was, by modern standards, small (Liverpool, with over 8,000 volumes in 1801, seems to have been the largest), and was accommodated, at the outset, in makeshift premises–-very often over a bookshop, with the bookseller acting as librarian and receiving an honorarium for his pains.
