While I was employed, books were my 'luxury' purchase - I still buy an
occasional book even now - but *after* I've read it from the library so I
*know* it's 'worth the money'.
I rarely read a book twice. There are so many others waiting to be read
that I feel that I am wasting time. The books I do keep are mostly
reference, I read them once then know where to get information later.
