What Google does is to compile information from the extant electronic
forms. It does not preserve the information (except in that some sites are
cached) and links to the sources.
If the documents under consideration were already in electronic catalogues,
then indexing would be quite worthwhile. The problem of collecting the
information from those documents is prohibitive, in some cases likely to be
more costly than simply preserving them.
Google does index some images and is developing some sound indexes (I keep
wanting to write indices, but of course that's another sort of index).
However, they are not based on content of the image or the sound but on the
associated electronic text at the site.
