In a previous column (MRSQ v. 8, no. 4, Winter 1989), I introduced several resources for teaching that have proven extremely useful over the past few years. In this column, I would like to add those texts that have served as reference sources. Although not used as heavily as the items on the prior list, these have answered questions or inspired ideas to help solve a particular instructional problem. This is a partial list and will be completed in a future column
