Book_count should solve it but is is not available in the template drop down list. Although it is well documented in the calibre manual.

Can anyone give me some help here?
You will need to have a column to tell you if the eBook is read or not. The first thing to do is make this column (I suggest Y/N unless you want it to be a date column). And then you have to populate this column. After that you can follow @chaley's directions.
