Yup. Shame on us. We're not really readers, at all ;-)

Bearing in mind the size of our little house, we reached a comfortable capacity some while ago--and still keep on buying.

The major reason for completing cataloguing just now is so that Looby Loo's grandparents don't buy her books she already has. Storing too many duplicates is just not feasible. Then there's my habit of forgetting which Folio Society books (what I lack in quantity I make up for in expense) I own.
