Often, the general scope and method of collecting each type of discovery request is prescribed by court rules. You may also want to consult the rules of court for your jurisdiction to determine how you must subpoena a witness, which disclosures must be made, etc. The current editions of the Federal Rules of Civil Procedure and of Criminal Procedure can be found both in print and on the U.S. Courts website. The rules of evidence for your jurisdiction will be important in determining the scope and method of how you may examine your witnesses and those presented by your opposing counsel. To search for state court rules, we suggest doing a subject search in either the Library of Congress Online Catalog or in WorldCat External, for “Court Rules–[State],” where [State] is the name of the state in which you are interested.
