Do you have a favourite non-fiction book about London? Perhaps it's a history. Maybe its a big, coffee-table photo book. How about a decades-old guide to London pubs? Perhaps you rate one of those 'secret London' books that tell you about the hidden corners of the capital. Biography, children's book, poetry collection, or even the A-Z.
Whatever it is, we'd like to know. If you know a book, or books, that every Londoner should read, nominate them below or tweet #bestlondonbooks. We're looking for non-fiction here — we'll tackle novels in a separate poll.
We ran with a similar question half a decade ago, so it will be interesting to see how the results have changed.
