#6 Editing and auditing

[howanu]

Maude added a Javascript book to her giftlist, but
changed her mind after a few days. She decided she'd
rather get a book on Cascading Style Sheets instead,
and editing her giftlist item. After thinking about it,
she went back to her original choice - but she had
forgotten the URL of the Javascript book. She'd like to
be able to see what the item as it was before she
changed her mind.
