The LED team scrutinises a small sample of each new volunteer’s submissions for accuracy, including accuracy of transcription from the original source. However, it is impractical to check every subsequent submission to this level. Users should therefore be aware that each subsequent submission is checked for the accuracy of easily verifiable data such as the publication details of the source and (where possible) the information provided about the listener and the music, and spot-checks are further scrutinised for accuracy of transcription.
