If our systems are giving our users relevant results, then that _should_ lead to more check outs and downloads.

'More' is a relative word. More than... what? 

I agree this is a useful general overview metric. I guess it allows you 
to compare one version of your software in your patron community to 
another version of your software in your same user community... unless 
something else changed in the meantime to change the net number of 
checkouts/downloads, which you should be cautious of.

But it doesn't let us measure it until it's deployed. It doesn't let us 
figure out _what_ needs fixing, what can be improved in a given system, 
or how. (Doesn't let us know if users do okay with a known title search, 
but miserable with a subject/topic search).  It doesn't let us evaluate 
potential changes until we deploy them over a large community in 
production and measure how it works. Etc. I doubt this metric is 
sufficient.
