That location is the London Family History Centre (LFHC), run by The Church of Jesus Christ of Latter-day Saints. There website states that “you can view images, print and/or download them to your memory stick on any of our computers.” Furthermore there is no need to book a seat, and it only costs 20p to print a page.
That is really just the tip of the iceberg as far as resources go at the LFHC. The resources available are staggering including Principal Probate Registry Copy Wills and access to the British Library Newspaper Collection online. If you have not been before and can get to London it is well worth a visit, it is like an Aladdin’s cave of genealogy.
But please don’t all rush at once, save me a seat as I have a lot of research to do!
