Surveys of the use of public libraries: which methodology to trust ?

Despite the concerns of professionals, who rely principally on the figures in the annual State Survey of Regional Public Libraries, the context really is favourable for the use of libraries - as demonstrated in the Crédoc survey in 2005. Although there are numerous surveys, they do not take into account the diversity of publics, of libraries and of their use. They frequently limit themselves to surveys within the public on a particular site. Whereas they need to be revised, by observing behaviour and cross-checked with surveys within the population of potential users.
