Under the law of the United States, civil discovery is wide-ranging and may seek disclosure of information that is reasonably calculated to lead to the discovery of admissible evidence. This is a much broader standard than relevance, because it contemplates the exploration of evidence which "might be" relevant, rather than evidence which is truly relevant. (Issues of the scope of relevance are taken care of before trial with motions "in limine" and during trial with objections.) Certain types of information are generally protected from discovery; these include information which is privileged and the work product of the opposing party. Other types of information may be protected, depending on the type of case and the status of the party. For instance, juvenile criminal records are generally not discoverable, peer review findings by hospitals in medical negligence cases are generally not discoverable and, depending on the case, other types of evidence may be non-discoverable for reasons of privacy, difficulty or expense in complying and for other reasons. (Criminal discovery rules may differ from those discussed here.) Electronic discovery or "e-discovery" refers to discovery of information stored in electronic format (often referred to as Electronically Stored Information, or ESI).
