Hello and thank you for contacting Just Answer. I am an expert here and I look forward to assisting you today. If at any point any of my answers aren’t clear please don’t hesitate to ask for clarification.
You can cite to other materials but it is useless to do so in Federal Court because the judges don't consider them authoritative and rarely consider them persuasive. You should cite only to case law, first from your circuit or the Supreme Court of the US and then from other circuits if you can't find anything in your circuit.
There is no "legal terms dictionary" that is used by the courts. you can cite to Black's Law Dictionary but, again, the court doesn't consider it as authoritative in any manner. Black's online is at http://thelawdictionary.org/ but I don't know that it is complete or the latest edition.
