The outer automorphism group Out(F) of a non-abelian free group
F of finite rank shares many properties with linear groups and the mapping
class group Mod(S) of a surface, although the techniques for studying
Out(F) are often quite different from the latter two. Motivated by
analogy, I will present some results about Out(F) previously well-known
for the mapping class group, and highlight some of the features in the
proofs which distinguish it from Mod(S).
