Librarians have the ability to contribute to the development of usability standards by thoughtfully developing and building on traditional information techniques. For example, I am currently lobbying the concept of a digital verso as a standard for onscreen publishing. The verso has seemingly been forgotten in the race to publish onscreen, I think because the people doing the publishing have not been aware of it's value. When people publish they usually think of the content - the chapters and the text. The verso - which connects the content to the larger information world and contains things like the isbn, publishing details and copyright information, is just as important to an onscreen document as it is to a printed one.
Indexing is another areas where our skills are in demand.
Related to this is metadata application. A government department recently said to us that they preferred our company because we had librarians involved with metadata application. This organisation didn't believe that an automated approach to metadata preparation was sufficient. And in order to achieve a consistently high quality of metadata, human intervention particularly by librarians as information specialists, was essential. Many librarians working in federal government departments will be aware of the government's online strategy.
