So, whilst sorting through the books for the library at work, there has obviously been a few that are now a little out of date (The Which? Wine Guide 1979, for example...)

I think the Portuguese and English dictionary I found today must take the award for being the most out of date though...


...the date at the bottom of the first page (The binding is quite damaged and the front cover is missing so this is what you see when you first look at it) is...

1773!
