This topic from Long and Short Reviews was an interesting one. Should I choose current books that would showcase recent times, or books from a wider range because they're classics?
In the end, I went with the classics. Well, some of them anyway.
I think it would be vital to preserve Jane Austen and the Bronte sisters for posterity. In the case of Jane Austen, I chose "Emma". I know many people prefer "Pride and Prejudice", but I've always found the wordplay and style of "Emma" to be more up my street.
As for the Brontes, I'm going to take a more unusual route and say I would preserve "Wuthering Heights" and "The Tenant of Wildfell Hall". Okay, I might agree to "Jane Eyre" at a push, but I personally have always preferred Anne and Emily over Charlotte.
And finally? It may be undeserved, but I'd add my own "Photograph" in there. It's my favourite, and probably the only chance I'd get at being remembered past my own lifetime.
So what would you include?
