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
- 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.
- 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.
- 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).
- 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.
