as with most other organized Internet collections, the resources found within each category are generally listed alphabetically. The specific conceptual relationships between resources, which we believe can facilitate individual and general resource use, are not indicated. While a listing within a broad category does offer some assistance in identifying relevant resources, such an arrangement requires a user to review an entire list to be assured that an appropriate resource has not been overlooked.
