There are two questions:
1) What percentage of the _current_ output of literature is being arXived?
2) When looking for cited work, what percentage could I find in the

1) For High Energy Physics (for which statistics covering all published
work can be obtained from SPIRES), the percentage of papers arXived is
almost 100%. I have no data to cover other areas, but it must be noted
that most areas of XXX are seeing increased depositing, whereas HEP is
almost static. I would hypothesise that this is because other areas do not
have a high percentage of all literature being archived.

2) For the whole of the archive this is around 30-40% (with the HEPs
having a larger percent), with the result that it will be another 10 years
before all cited work has been archived (assuming the typical lifespan of
a paper is 5-7 years). This length of time could be reduced by authors
archiving existing literature.

All the best,
