Experience and anecdotal evidence suggest that men and women use—or do not use—public libraries in different ways and amounts. Compared to extensive research on male and female differences in reading, computer use or within the context of the school library, there is relatively little descriptive research showing the library preferences of adult men and women. This study analyzed over 1,200 user responses in a survey conducted as part of a strategic planning process of an affluent public library. Male patrons in many respects were simply below-average in many areas (fewer visits, fewer services or resources used) but also showed distinctly different choices in a few areas, mainly related to electronic and business-related items. They also are almost completely uninterested in children's areas, a sharp contrast with adult female patrons). Male usage is distinct enough to warrant special attention from library planners. The results help library managers understand better what different patrons already use, and those areas where greater marketing or different strategic choices may be needed.
