Electronic discovery (also e-discovery or ediscovery) refers to discovery in litigation or government investigations which deals with the exchange of information in electronic format (often referred to as electronically stored information or ESI). These data are subject to local rules and agreed-upon processes, and are often reviewed for privilege and relevance before being turned over to opposing counsel.

Data are identified as potentially relevant by attorneys and placed on legal hold. Evidence is then extracted and analyzed using digital forensic procedures, and is reviewed using a document review platform. Documents can be reviewed either as native files or after a conversion to PDF or TIFF form. A document review platform is useful for its ability to aggregate and search large quantities of ESI.
