hi George as far as i know, Google does enforce limits on file size, but what it is may vary over time ...
from the perspective of electronic theses, a while back NDLTD was advised by Google that all theses should be single-PDF documents, as that fit in with their model - their digital object unit is apparently a single file. of course this does not work for most theses, and it was never implemented widely! so if every file is considered independently, Google's processing will apply to individual files ... hence some may be filtered but others retained. hope im not too much off the mark, and this helps :) ttfn, ----hussein ===================================================================== hussein suleman ~ [email protected] ~ http://www.husseinsspace.com ===================================================================== George Kozak wrote: > Hi... > > We (at Cornell) have discovered a weird problem with Google harvesting > and wonder if anyone else has seen this.
