Certain questions come up time and time again. You can save time by keeping a list of the most frequently asked questions and their answers; each time one of the questions on the list gets asked you can just cut and paste the answer.
FAQs can also work as a knowledge management tool. Although you may answer certain questions frequently, other staff members may not. One solution is to have these questions and answers saved centrally so they are accessible to all library staff.
To get even more bang for your buck, put these questions and answers on your intranet or website so your end users can easily find them. For example, Courthouse Libraries BC has a list of Asked and Answered questions on its website; based on a list that was originally developed as a private tool for Courthouse Library staff.
