Crime Library contained an extensive collection of crime related articles, which were separated into categories: Serial Killers, Notorious Murders, Criminal Mind, Terrorists & Spies and Gangsters & Outlaws. Each category was then broken down into further subcategories. For example, within Serial Killers were the subcategories Most Notorious, Sexual Predators, Truly Weird & Shocking, Unsolved Cases, Partners in Crime and Killers from History. Crime Library also featured photo galleries. These may have had anywhere from 10 to upwards of 100 slides. Some photo galleries were focused on a specific case, while others were lists of crimes linked by a theme (e.g., "Baby for Sale," cases where a person was arrested for allegedly attempting to sell his or her child), or collections of unusual booking photos.
