A handy class used to parse Amazon book links, extract normalized ISBN13 from them and decide whether they point to a book or some other content.
Add this line to your application's Gemfile:
gem 'amazon_book'And then execute:
$ bundle
Or install it yourself as:
$ gem install amazon_book
link = AmazonBook::Link.new('https://www.amazon.co.uk/dp/009957506X/')
# => #<AmazonBook::Link:0x007fd15515d7a8 @url="https://www.amazon.co.uk/dp/009957506X/">
link.book?
# => true
