The web is poorly organized because it maintains no distinction between Works and Bullshit. Nor does it have any concept of a Work, only of a "web page" which is a completely artificial construct.

If you put a novel online, there's no way to specify, in its full generality, in a machine-readable manner, that the novel is a single, individual Work. Instead, you must trawl through individual archives to specify this to each one, each in its own unique manner. This is called "posting the novel" and it is tedious.

The inability to search through all, for example, scientific works and ONLY scientific works, is a liability. So is the inability to specify a search through works which you have already read. Nor by their publication dates.
