Rather late on the reply, but I was just doing something similar. I needed to generate an alphabetical index of publications (all PDF) and wanted it in a nice HTML table with other pertinant metadata (pages, creation date, etc.).

What follows is just a bit of cleaned up PDF reading code:

opendir DIR, '.';

my @pdf = sort { $a->{Title} cmp $b->{Title} }
          map  { scalar( get_info($_) )      }
          grep { /\.pdf/i && -f $_           }
          readdir DIR;

sub get_info {
    # Get basic PDF metadata.
    my $file = shift;
    my %info;
    
    my $pdf = PDF->new($file);
    
    return undef unless $pdf->IsaPDF;
    
    $info{Filename} = $file;
    $info{Size}     = -s $file;
    $info{Pages}    = $pdf->Pages;
    for (qw(Title CreationDate ModDate)) {
        $info{$_} = $pdf->GetInfo($_)
    }
    return( wantarray ? %info : \%info );
}

That opens the current directory and results in an alphabetically sorted (if you wanted it sorted by different criteria just change the sort {} section) array of PDF metadata info hashes. $pdf->[0]{Title} is the title of the first PDF in the array.

print "$_->{Title}\n" for @pdf;

Will give you a plain text list of all the document titles. If you only want titles just delete all the hash stuff in the sub and return the title scalar only.
