You can share your photos with us online, check out our videos or connect with us on Twitter or Facebook.
You can also find us on Meetup, Upcoming and TripAdvisor.
To find out more about our collections and the work of our curators check out the newly-launched blog, Stories from the Stores.
You can also contribute your knowledge and memories to our pilot object wiki that features a selection of objects from our collections or search 230,000 objects from the collections of the Science Museum, the National Media Museum and the National Railway Museum.
If you're interested in how we're planning to provide access to re-usable and shareable collections data, there's a very informal, slightly more technical wiki with more information about museum APIs. We're also running a competition, Cosmic Collections, to encourage design, astronomy and web enthusiasts to create websites with our beta API that provides access to data about the objects in the Cosmos & Culture exhibition. Talk to us @coscultcom on Twitter for updates and FAQs.
