How much time is required of a volunteer? The answer depends on your interests, skill set and other commitments. The length of a typical BookStore shift is 2-3 hours while the length of a typical Book Sale shift is 3-4 hours. Other organizational needs may require more or less time, depending upon the need. Be assured that you will always work with a great group of people from Castro Valley!
