If your potential readers are extremely mobile or use computers in their work, it could be an excellent approach. For instance, Johnny Hamilton of Construction Trades Press is especially interested in creating electronic documents that can be used on location during construction jobs. If your audience is computer-comfortable, think about what formats will make the most sense. It produces a document that looks exactly like the printed version, which maintains quality and consistency. Publishers are also quite comfortable with this format because many of them are already using it to produce camera-ready versions of their books for print production.
Images are easy to include.
It also is relatively easy to create. However, encryption is still an issue. Images can be included, but sparingly. The format is now available on PocketPC handheld devices and will be available for desktop and laptop computers in late 2000. Although you can offer MS Reader editions from your site, encrypted versions will initially be available through only limited outlets.
