It is true that more women than men are registered with and use the public library—but the preponder- ance is not overwhelming (Table 11). Actually, women con- stitute from about one half to two thirds of the library regis- tration and the library clientele (Table 12). This ratio is dependent upon two factors. In the first place, the larger the city, the larger the proportion of men in the li- brary clientele.® Secondly, men make relatively more use of the reference services of the public library,” whereas women make more use of the circulation services.’ Incidentally, there is a different pattern in the use by men and women of other sources for books in the community: women (housewives) are more likely to use the rental library and to borrow books from friends, whereas men more often buy the books they read (Table 13).
