Reader's advisory involves connecting patrons to books through a variety of techniques. It helps patrons understand their reading tastes and can be applied to both fiction and non-fiction materials. To be effective, reader's advisors should read widely across genres, learn to think of related books, and familiarize themselves with review and book resources both online and in print. The reader's advisory interview involves listening to the patron, asking descriptive questions, restating their interests, and providing options without judgment.
