The conference goal is to build and further a vibrant library assessment community by bringing together interested practitioners and researchers who have responsibility or interest in the broad field of library assessment. The conference provides a mix of invited speakers, contributed papers and posters, and workshops that stimulate discussion and provide workable ideas for effective, practical and sustainable library assessment. This biennial conference builds on the success of the first three conferences held in Charlottesville (2006), Seattle (2008), and Baltimore (2010).
