D3E Publisher's Toolkit
The D3E Publisher's Toolkit processes HTML files (e.g. generated from whatever your favourite editor is). The toolkit generates a frames-based environment with automatic hyperlinking for navigating around sections, checking citations and footnotes, and tight integration with a discussion space for critiquing documents (see some screenshots and example applications). There is no known limit to document size (in fact its navigational support is particularly useful for large documents), and the output is platform and browser independent. See the annotated interface screenshot for an example. See the User Guide for full details.
Open University staff should check out the LTS OU-D3E service and obtain the OU-version of the toolkit.
In v5.0 there are two web discussion systems to choose from, depending on your personal preference and what platforms and software you already use. v4.1.1 generates discussions only for HyperNews.
