Today, Monday 9th June 2014, sees the opportunity for the general public to apply for free used microfilm from The National Archives. The redundant microfilm is being disposed of due to increasing online access in the reading rooms at Kew. The offer opens today and closes on Sunday 27 June at 5pm. The films will be allocated by lottery, a draw will be carried out using numbered balls, with a separate draw for each batch. Requests are only accepted for whole batches. The films are free but successful applicants must arrange removal and meet the costs of removal from The National Archives.
There's more details, including how to apply to join the lottery at The National Archives website.
