The Joint Usage Statistics Portal (JUSP) (jusp.mimas.ac.uk), created by five U.K. libraries in 2009, gives participating libraries a single point of access for electronic journal statistics. It provides its more than 160 participants, including 140+ academic libraries in the United Kingdom, as well as 21 publishers and 3 intermediaries, with COUNTER-compliant data, harvested using the SUSHI protocol. Data anomalies are referred back to the publisher for correction prior to releasing to the libraries, so data are quality-assured. Both journal level (JR1 and JR1a) and summary reports are maintained, as well as experimental reports. JUSP benefits publishers, as it provides customers a complete record of usage, including that from intermediaries, and it shows a proactive interest in customer service. Libraries benefit as it saves them time, data are quality-checked, and it allows for evidence-based collection decisions.
