The last time I built an application using the Google Java API the
documentation stated a limit of 1,000 queries per day, which was in
2005. It probably hasn't changed, although I'm not sure. Perhaps a way
around that is to cache queries into another file and then first query
the cache before sending a query to Google. I guess that the idea is not
to have cover images stored locally because of the size of the files,

Is there any word on a limit to the number of hits per day on the Google
API? I missed it in the docs if it's there, only saw an ominous warning
that you might see the service temporarily disabled if you generated an
'unusually high number of hits' during development.
