The Heritage High School library is an excellent resource for all events. For students that are interested in interpretation events, the librarian can help you find plays and short stories written in first person. The library is also an excellent place to start researching debate theory to make yourself more comfortable with argumentation and strategy.
These websites have been approved by the National Forensics League (NFL), the governing body for speech and debate:
