Alongside the landmark Radio 4 series on the project, you can learn more about the objects already in the collection on BBC TV and local radio.
Throughout January and February, The Radio Cafe on Radio Scotland discussed some of the objects selected by the museums in Scotland, both the story behind each object and the issues it opens up.
Radio Scotland's Past Lives also featured objects nominated by you.
Add your object
You can be part of this by contributing to what could be the world's biggest digital museum. Add your object and help us tell A History of the World.
If you have an artefact which shows the connection between your area and the wider world, maybe it's something of importance to your community or which shows how lives have changed, go to the website where you can add your suggestion to the collection.
Take a photo, upload it to the website and add a brief description. You'll receive confirmation that your object has been added to the collection. Go to A History of the World website for more details.
What will you add?
Some well-known personalities have now added their object including Hardeep Singh Kohli and David Attenborough. Hardeep chose a painting by Scottish artist Tony Scullion that has links to his Scottish and Indian heritage.
