I also get a little annoyed when professors speak of African-American history
through the eyes of slavery only.  African-Americans have contributed a great
deal to America and this should also be emphasized.  One of my favorite books
is African-American Firsts by Joan Potter with Constance Claytor.  It is about
famous, little-known achievements made by African-Americans.  It certainly
uplifted me and I'm sure it will do the same for ALL students of history!
