I don't, of course — we (VERY POINTEDLY) do not have the shelf space. My parameters of purchase are: was I previously aware and desirous of this particular author/book? Do I enjoy the work of the person selected for the introduction? There are more than a few NYRB editions that I've bought solely for the intro. Sometimes that is as far as I read.
Until this morning, I was not at all aware of Józef Czapski — but with this excellent introduction and this celebration, I have now put Lost Time: Lectures on Proust in a Soviet Prison Camp and Inhuman Land: Searching For The Truth In Soviet Russia, 1941-1942 on my list of purchases for my next visit to BMV's flagship store in Toronto's Annex.
