Bad ISBN edit

Latest comment: 9 years ago1 comment1 person in discussion

Because it is causing a Checkwiki error #73: "ISBN-13 with wrong checksum", I removed the ISBN:

ISBN 978-0-521-87501-0 Parameter error in {{ISBN}}: checksum

An ISBN alone is not a reference; when it's a bad ISBN, it's useless. Knife-in-the-drawer (talk) 14:40, 30 April 2015 (UTC)Reply
