Text Errata

Errors in the texts appear below as they are discovered. If you find an error that is not reported here, please email it to chaynes@indiana.edu. The first person to report an error will be credited on this page (username in parenthesis) and receive a bit of extra credit. 

Those that begin with "NOTE" are particularly serious and will cause problems if not corrected. Those that begin with "Typo" are minor and probably would not confuse you. Others might cause problems if not corrected. Inserted or changed text is bold.
