Librarians have a weird sense of humor. This was the old joke: “The internet is like a library with no catalog where all the books get up and move themselves every night.”
It has now been replaced with: “The internet is like a library with a thousand catalogs, none of which contains all the books and all of which classify the books in different categories – and the books still move around every night.”
The problem now is not that of “finding anything” but finding a particular thing. This link gives older students some pointers to help them become effective internet researchers.
