Why not use a DOC format?
When we began developing our Bible products, we looked at the DOC format, but since our direction and desire were to provide specific Bible study tools, we needed a more complex reader/database structure to handle references, hypertext, smart lookups, and original Greek and Hebrew languages, for example. Problematically this required building a proper base to display these tools on. Most generic readers do not understand Bible references, for instance, making it impossible to perform a search or look up a word. This is why we do not use a generic reader. In the future, using our BibleReader, you may be hyperlinked to many Bible study tools from a specific verse. We wouldn’t be able to do this in a generic reader.
