I don't understand who refer report 's database, for example there are 2 databases All databases, whose are they? Would you organize reports by publisher and database title? I would also need to split publishers too, for example I need to split Elsevier statics for Cell press journals. There's an other solution?
I'm not sure about the first part of your question as we are just a single library, not using as part of a consortium. But for your Elsevier titles you might try "tagging" the titles for Cell Press so that you can view/report on those titles separately. You could do manually or with a title upload.
