It has long been my practice that when I’m in bookshops, often, and I see a book I like, frequently, but not keen to buy it then and there, I add its ISBN to the note section on my phone. Potentially I can find it much cheaper online or perhaps more info, reviews and indications of whether it’s any good or whether there might be a better book on the same topic. Or even, given my fetish for nice bindings, a nicer edition. Or just simply the space to have second thoughts.
Having run out of storage space on my phone for such notes, here is the current list. This way at least, they’re stored somewhere vaguely useful.

There was actually more fiction on the list but it appears that I’ve managed to buy most of the fiction I was keeping track of. There’s a few books I keep meaning to buy but never quite get round to, for which I haven’t recorded ISBNs such as Romulus, My Father, Cloud Street, a couple of those classics that have been reprinted in nice leather plus a few penguin classics. That’s all that comes to mind for the moment. I daresay there will be more.
