Have you ever done a bibliography before?
Have you used APA or MLA style before?
If the answer to either or both of these questions is "No," then we
STRONGLY recommend that you do the exercises in this section.
The option to skip the exercises is provided for the convenience of those who may
have already done them once and simply want to review the other material
in the chapter or who experienced a technical error.
I'll do the APA exercises.
Ok, I'll do the MLA exercises.
I'd still like to skip this section.
