18. Panel Intro • Questions, questions, questions !!! • Please write notes and pass them to aisle and to front. • Please raise hand till I acknowledge you. • Please state name and affiliation, slowly. • Be brief as you ask a question. • Theme: How does the state of the art in today's digital libraries compare with digital libraries in general? • Challenge of supporting math content as we do: information retrieval, blogging, authoring, web display,…

19. Initial Questions (Robert Miner) - 1 • Relative to your initial expectations, what are the areas where the digital math library projects you are associated with have been most successful? Least successful? How would you compare the success of digital math libraries to digital library projects of similar scope in other areas? Do you think that digital math libraries are currently viewed as successes by their users? By the larger library institutions of which they are a part? • Do your users have expectations for digital libraries that you have a hard time meeting due to technological limitations in dealing with mathematical content? Conversely, are there areas where you are able to provide users with tools and services that take advantage of the mathematical nature of your content that aren't generally available in other digital libraries? Are the gaps in software support for mathematical content so severe that they limit the usefulness and popularity of digital math libraries, or is it mostly a question of mathematical content requiring extra time and effort in order to achieve adequate quality and ease-of-use for end users? Which software gaps are most serious for you, and how do you work around the problems now?
