Brighton Dome Memorabilia (Brunswick BN3)

I just started vounteering at the Dome on the Heritage Volunteer Team and we are hoping to build an archive of materials from its history - including the Corn Exchange & Pavilion Theatre, as well as the main Concert hall itself. If anyone has any old programmes / posters/ photos/ newspaper articles etc , which they would like to donate, I would be interested in hearing from you. Many thanks.
