Only the first results count: user-feedback-modified relevance ranking in E-LIB Bremen

Up to now, library catalogue ranking methods have largely ignored user feedback. However, in 2011, the State and University Library Bremen (SuUB) developed modified ranking methods for its own discovery system, Electronic Library Bremen (E-LIB Bremen). These make use of popularity factors such as click statistics and information about the number of editions published as well as how many copies of a given title are available. This customized development has enabled fast and flexible new retrieval functions to meet the needs of local users.
