The following is a list of freely available sleep datasets with overnight sleep recordings obtained using polysomnography and can be used to develop algorithms for automatic sleep scoring.
Number of recordings: 197
Scoring method: R&K
Description: This database consists of overnight PSG recordings from two different studies. It contains EEG from Fpz-Cz and Pz-Oz chabbeks, EOG (horizontal), and submental chin EMG.

Number of recordings: 8
Scoring method: R&K
Description: This is a subset of the Sleep-EDF Expanded Database. Initially, this was the only sleep database available but has now been made obsolete with the availability of the larger database.

Number of recordings: 108
Scoring method: R&K
Description: This database consists of 92 pathological and 16 healthy recordings with at least 3 EEG channels (F3 or F4, C3 or C4 and O1 or O2, referred to A1 or A2), EOG (2 channels), EMG of the submentalis muscle, bilateral anterior tibial EMG, and respiration signals.
