E-Book Policy

E-books can vary considerably in their quality and aims. Here, we would like to set forward the principles which we aim to follow in the generation of e-books and in the provision of e-books for sale.

Our Principles of E-Book Creation

  1. The resolution of all illustrations and images are the highest possible. This means that the quality of the image in the e-book should be higher than in the corresponding print title.
  2. All maps, charts, and chartlets are vector files wherever possible. This means that the quality of a map in the e-book should allow for more use (including zoom and focus without loss of resolution) compared to the corresponding print title.
  3. There is no Digital Rights Management (DRM) applied on an e-book. The e-book is licensed to its purchaser. If a purchaser wants to share a purchased e-book, they may purchase additional copies in correspondence with the number of people they wish to share the content with (i.e., gift the book to).
  4. An e-book should be considerably cheaper than the corresponding print book.

The above principles mean that the size on disk of the e-book will be increased by the higher resolution of the included graphics.
