A subpoena is the legal tool used to compel a witness to appear and either provide testimony or produce records. There are two common forms: ad testificandum, which requires the witness to testify, and duces tecum, which requires the production of documents or other records. Grand jury subpoenas are a specific type of subpoena used in grand juries, but they are still subpoenas. By contrast, a national security letter compels production of information without requiring the witness to appear, and a search warrant authorizes a search of premises rather than compelling testimony or records from a witness.
