Another great source is any hymnal. They have lots of selections in a lot of styles, keys, time sigs, etc. Just read the bottom line of the four part songs.

If the notation is what you want to become familiar with, you might begin with reading, away from the instrument. First look at the notes and say "D, Eb, F, A, C..." or whatever is printed. Then call out the solfege: "Do, Re, Fa, Mi,.." Then sing the notes.

Remember most of the older hymn setting were meant to be sung at sight.
