The Consortium of Academic and Special Libraries of Saskatchewan was established in 2016. It is a renewed and expanded form of the Regina Library Information Network (RegLIN) which was incorporated in 1990. The idea for RegLIN originated in 1987 when the University of Regina Library and several other libraries in Regina partnered to acquire integrated library system software. The software was hosted at the University of Regina and was structured to provide separate library catalogues for each partner. From the beginning, RegLIN embraced cooperation for cost savings and efficiencies, while also valuing flexibility, diversity, and the institutional mandates of its members. RegLIN’s transformation into CASLS began in 2014 and was completed in 2016. With renewed focus and an expanded membership, CASLS has built on RegLIN’s 26 years of experience and continues to support inter-institutional collaboration on innovative solutions for library users today.
