E-Libraries and Distance Learning
After 20 years of digitization efforts, hardly a single type of library information resource remains that has not shifted, at least to some extent, to an electronic, Web-based format: information about the library itself, catalogs, indexes, dictionaries and encyclopedias, books and journals, tutorials, reserve materials, and reference services. From the perspective of accessibility, design in the online world matters as much as it does in the physical world.
