Hello,

could someone explain to me what is the meaning (functionnaly speaking)
of this portion of code :
(C4/Circulation.pm)
         # check if the book is in a permanent collection....
         my $hbr      = $iteminformation->{'homebranch'};
         my $branches = GetBranches();
         if ( $hbr && $branches->{$hbr}->{'PE'} ) {
             $messages->{'IsPermanent'} = $hbr;
         }
