We know budgets are tight. You need to stretch every textbook dollar. Once you know the facts, you'll agree that plenty of people lose.
Many people think that publishers and used-book companies work together.
Used-book companies feed off this generosity, collecting samples and reselling them without our approval. In the long run this practice shortchanges educators and threatens the quality of our materials. Teachers Purchase our textbooks from a used-book company, and you give up customer service from knowledgeable reps and consultants who know our books and understand your needs, free teacher support materials designed to enrich your curriculum and make your job easier, and free inservice training from professionals in your field. Of course, used-book companies don't share their profits with our authors, whose hard work goes unrewarded. Don't cut corners on quality and service.
