The Round Rock Public Library offers an introduction to Microsoft Excel. The class meets from 6:30 to 8:30 p.m. Wednesday, Sept. 16, 23, and 30, in the first floor computer lab.

The class is designed for Excel beginners, and will teach you about the program's features: how to navigate, to enter and format data and text, and to use basic formulas.

Participation in computer classes is on a first-come, first-served basis. The computer lab doors will open 5 minutes before the start of the first class, and the first 12 people will get seats for the 4-session class.
