For some authors you can also get information from Something about the Author, or from book jackets. Make sure you have a list of the author's books. Make sure your library has plenty of the author's books. Introduce the author's books to the students. Assign them to read something by the author, or have the school librarian or the teachers read the author's books to the students.
Some schools buy paperback copies of the authors books and give one to each of the students.
Give students some fun assignments that relate to the concepts illustrated by the author's books. Plan the author visit for a time when writing is a major curriculum focus, for example, during a Young Authors fair, or during preparations for a school writing contest. Invite parents in for the author presentation. Parents frequently get as much from the author visits as their children. Prepare the students for the presentation.
