For your convenience, copies of the overheads used in class are available both in the EMS library, and on this site. The pdf files below may be printed an used fro supplemental note taking in class.

These resources are provided to ease the burden of note taking in class, not to supplant it. These overheads are not self-supporting and are not self-explanatory, absent the narrative given in class. I encourage you to not use these resources as an alternative to attending class.
