A team of volunteers has been given a tour of Derby's mothballed Industrial Museum to help bolster its Wikipedia entry.
The Silk Mill, which closed earlier this month, is the first British museum outside London to be visited by a team from the online information site.
The volunteers - known as Wikipedians - made notes and took photos of the most interesting items.
It follows a similar effort with the British Museum in London.
The council-owned museum houses historic items from Derbyshire's role in the Industrial Revolution of the 18th Century.
Wikipedia has more than 10,000 volunteer editors in the UK who contribute to the website's three million entries.
Terence Eden, a member of the visiting team, said: "If we want to get people learning all about the fantastic history of Derby, the only way they can see that is going to be online.
"Not everyone can come to Derby and even if they could the museum is sadly shut anyway.
"If we can take some of the pictures and information and release it to the world, I think that's a fantastic objective."
