Hmmm...several fingers pointed at referencing the hash so far in this thread...

The %booklist_1 hash is populated from a previous query, like this: 

$sql = "SELECT book_id FROM booklist_table WHERE (expected_publcn_date
+ >= '".$start_date."' AND expected_publcn_date <= '".$end_date."')";
$sth = $dbh->prepare($sql) or die("Could not prepare!" . $dbh->errstr)
+;
$sth->execute() or die("Could not execute!" . $dbh->errstr);
while ($book_id = $sth->fetchrow_array()) {
    $booklist_1{$book_id} = 1;
}
$sth->finish;
