If you're curious about the meaning of 'Sprzendajemy Polskie Zsiazki' - emblazoned as it is on Waterstone's window in the Arndale Centre - wonder no more.

It's simply to let members of Luton's growing Polish community know the shop now stocks books in their home language.

Manager Annie Dufall explained it was in direct response to an increasing number of requests for Polish literature.

She said: 'We liaised with a supplier in Poland who recommended the current best sellers there, as well as one who told us what was popular here.

'We now have a range of fiction, non-fiction and children's books on our first floor.

'We have a good choice of popular Polish authors such as Maja Kossakowska, Andrzej Sapowski and Jacek Komuda alongside titles translated from Dan Brown, Stephen King, Wilbur Smith, Doris Lessing, Nora Roberts and others.'

The Luton branch is one of 25 country-wide selected to stock Polish titles. If the initiative takes off, the number and range will be expanded.
