A response to that need would be to have a page that links to admissions statements from each program. The page may not be designed to be accessed directly. For example, it may not have any links to the program's home page or other pages within the site. The moment you click on the link, the instructions on how to navigate disappear. Rather than going directly to the needed information, the visitor is routed past other structures and topics which must be assimilated before they can reach their goal.
Web users are generally intolerant of such required diversions.
Maintaining a page linking to such frames sites, each with their own set of instructions, each structured differently, and each using its own vocabulary, is difficult and time consuming. I recently attended a webmaster's conference in which this topic came up repeatedly. Large organizations are facing a common problem - even with nice, well organized corporate home pages, Web sites within the organization tend to adopt practices that defeat efforts to build an interconnected, coherent web of information. So a network that is twice as large will be four times as valuable because there are four times as many things that can be done due to the larger number of interconnections. Conversely, a network of information that is subdivided into disconnectd units is less useful.
