If you manage your eBooks collection with Calibre, this tool will allow you to generate an OPDS compatible XML catalog (Stanza and Aldiko use this standard), complete with cross-references, and external links to interesting web pages about your books.
This catalog can be used with OPDS compatible reading software/devices to browse your catalog online and download items of interest.
In addition, an HTML version of your catalog can also be generated, allowing access from any browser-based ebook reader (e.g. a netbook with Firefox and ePubReader).
