Well, getting the pagelist itself is pretty simple:

    [[{=$FullName}]] - {=$:BookAuthor} - {=$:BookTitle}

The tricky part so far is "when $:BookAuthor begins with 'A'";
ideally (for efficiency/speed reasons) it really should be coded as 
part of the (:pagelist:) directive and not a pagelist template.

The best idea I have so far (just thinking about it off the top of
my head) is

    (:pagelist $:BookAuthor=A* fmt=... :)

but this may require some substantial coding in (:pagelist:) to
make it happen.  Similarly, for sorting on a page text variable,
we'd have:

    (:pagelist order=$:BookAuthor ... :)
