Probably the only generalization about the Internet is that there is none, which is to say that users can have nearly any experience they desire. Internet users are not prisoners – they are responsible for their experience since they can generate nearly any experience they wish (other than an in-depth historical analysis).

I wonder do users sometimes feel like prisoners inside our information systems and catalogs. They bump into walls all the time, and can do little to manage their experience.

The library does not have a singular network presence. There may be a main website, but the library also syndicates its presence to other venues (e.g. RSS), has unbundled to social sites (e.g. Facebook), and sources activity in the cloud (e.g. LibGuides).
The collection remains central to the library experience. However, as library services evolve beyond the collection so it makes sense for discovery services to represent more of what the library does and can provide - to move from 'full collection discovery' to 'full library discovery.'
