I created my LibraryThing account on 10 May 2009; I think I had only two or three dozen books back then, but was already a regular Amazon customer, buying new ones whenever I felt I could afford it.
I kept it while the number kept rising; while I was discovering Kindle and the possibility of obtaining out-of-copyright books for free from Gutenberg; while emigrating and discarding probably more than a half of my prints; while extending my library in Scotland again, even over a hundred items; while returning with – Kindle aside – only six of them . . .
Recently I realised that keeping (and updating) the account more or less solely for the contents of my Kindle was largely pointless. And on Wednesday I deleted it.
