Maritime Conventions and Codes on Amazon

wp-1481562626266.jpgThroughout the recent posts on this blog have been references to various International Maritime Conventions and Codes. Now that all the key certificates have been covered, it is probably a good time to provide a quick reference to where to purchase the source publications.

Where to find the publications on Amazon

When I started building this post my intention was to give links to each book. Unfortunately, I was soon thwarted by the high range in prices being offered on line. In order to avoid providing links towards overpriced I have instead given some search links that will allow a quick check of what is currently being offered on-line.

Before buying through Amazon then it is recommended to check the suppliers and prices IMOfrom the IMO, at their publication page.
