One way to find out which types of booktalks work best is to create an evaluation form for the audience to complete. Some booktalkers may have a natural inclination for first-person booktalks, while others may present typical third-person book talks, or a book talk that's been digitally enhanced to keep the interest of the audience. The audience will also determine the length of the presentation, how many booktalks are presented, how much information to disclose, and the length of the individual booktalks. The audiences of booktalks are broken down into the following categories: students (broken down into the sub categories: young children, older children, and teens), adults, senior citizens and professionals (for librarians and educators).
