This item is a lot of three O’Reilly Perl books. All books are in very good condition but one book has the word “Admin” written on the top (see photo). No writing on the inside of the books on the pages I checked. – Perl In A Nutshell, 2nd Edition – Learning Perl, 3rd Edition – Perl Cookbook, 1st Edition Please see the photos for the best description of the condition. Thank you for viewing.
