Most books published by the International Maritime Organisation (IMO) and Witherby/Seamanship-International are available for download as eBooks.
How they Work:
Our ebooks are in “ebk” format, which require three pieces to work:
- The ebk reader application, which can be downloaded for free here, or comes as part of the excellent IMO Bookshelf CD-ROM, available for the price of shipping. Note: A Windows PC is required for both of these applications.
- An ebk file, downloadable from the book’s page on NauticalMind.com (eg for IMDG) or through our partners’s distribution site — either the IMO’s or Witherby/Seamanship’s Virtual Publication sites.
- An activation code, which can be purchased from a product’s page on NauticalMind.com (eg for MARPOL) or by calling 1-416-203-1163/1-800-463-9951. Your activation code will be sent to you shortly after your credit-card transaction is processed. This is almost always within 24 hours of your order submission.
Download the EBK file, unzip the file, and open it in the EBK Reader or IMO Bookshelf, then enter the activation code when prompted. For technical support, please don’t hesitate to contact the Nautical Mind.
EBK eBooks are protected against piracy by the IMO and Witherby with Digital Rights Management. The default license is for a single user on a single machine, and cannot be shared. If you require multiple licenses please contact us by phone or email. Volume prices are available.
