To see what we've already read, look over there at the right hand sidebar and scroll down past the lists of arrivals, bookshops, writers, publishers etc. and you'll find them all in order with the most recent one up at the top. I think it's a pretty good range, given the constraints on choice, i.e. the book has to be available in libraries and shops 'everywhere' - that's a limiting factor, especially where recently published books are concerned because they may well not have filtered through the library systems to the same extent that ones which have been around for a while have done. If you prefer to own your own copy, that's much easier nowadays with the proliferation of e-books, the reach of online retailers, and efficient 'bricks and mortar' booksellers who can order anything (in print) not already on their shelves, but what it all comes down to is trying to choose something which anyone, regardless of their location and preferred method of obtaining the book, can get their hands on.
Those are the practicalities which have a bearing on our choices, but what about the fun bit: the genres we may like to consider, the individual authors, periods or countries of origin? What takes your fancy? What sort of thing would you like to read with the group? Should we do other books by authors we've already read? Read more in translation? Are you in the mood for more classics (Lady Audley's Secret went down well)? Something very contemporary, perhaps? Please let me know what you think.
