At the top of page 54 in the printed book, maps are described as:

small, fix-sized structures

Shouldn't they be "fixed-size structures" instead of "fix-sized" ones?

You might be right. We're entering nuances of English and I'm not confident here smilie
The point is that I advise using maps for smaller structures with predefined elements (usually something like data structures). Note however that this advice may become obsolete, possibly even in upcoming Erlang 18.
