i assume you wish to know the basis of the attorney's objection in court, correct? the attorney is generally objecting to evidence offered, or about to be offered into evidence. the idea is that the evidence does not meet the standards for admission of evidence at a trial. the witness about to offer evidence may not have personal knowledge of the facts. the witness only "knows" because of what some other person told her. hence, "objection,hearsay." books are published (usually by west publishers) that contain the rules of evidence and procedure in the varying courts. there is, for instance, a federal rules of court that govern such matters in all federal courts through the us. each state will also have book of the state's "rules of evidence" that will generally govern the state's courts throughout the state. i do not know for what purpose you want the information, so it is a problem directing you to the best source of the info. are you located near a law school" the school bookstore will have varying kinds of books (in addition to text books) to assist the law student in various class subjects. some are quite basic and are generally referred to as "outlines" of a particular subject. there are numerous on line resources for this info and you will pull up a bunch if you put "objections to evidence" in your search box.
Either one would be good. It depends on what kind of experience you are looking for. The Federal one would handle bigger cases but not as much variety.
