PhysioNet users with an interest in sleep physiology now have access to the web site of the National Sleep Research Resource (NSRR), which hosts large annotated collections of EDF polysomnograms and related clinical data elements from well-characterized research cohorts and clinical trials. The first data set available includes over 8,000 studies from exams 1 and 2 of the Sleep Heart Health Study, with scheduled new data releases every quarter from additional data sets. NSRR also provides open-source software for viewing and analyzing these data.
