Too many resources in the CMO

When I first started with the CMO I used to add everything.  So now in my added resources I have tons of library books that we’ll never read again.  I listed all kinds of the YWAM missionary books that I really don’t want to have listed individually and I have some other library books that I don’t want to forget about, but I’m not sure that I want them showing up in my added resources either!  I would like to be able to print up a list of my added resources so that I can take notes on it, but mostly keep it to curriculum that I own.  How do you all keep track of your resources?
