I guess this refers to the file perllocal.pod. A not-so-well-known feature of perldoc is that you can omit the prefix perl, so perldoc local will do the same as perldoc perllocal (unless you have a local.pod on your Perl path).

In my experience it returns a rather useless subset of installed modules - apparently only those I built myself using make install, i.e. where the module author used ExtUtils::MakeMaker. Modules I have installed with the package manager or with cpanm are not listed there.

The way how perllocal.pod is maintained explains why you won't find anything about it on https://perldoc.perl.org.
