This is a visual browsing tool that maps objects by date of creation onto a timeline.
The circles indicate where online objects feature on the timeline.
- Each circle represents at least one object within a span of 100 years around that point.
- The size indicates the relative number of objects at that point on the timeline.
- The colour indicates which objects on the timeline are visible on the current page of results.
- Hover over a circle to see how many objects are represented at that point in time.
Click and drag the black bars to the left and right of the timeline to focus on a particular period of time.
Click on the buttons above the timeline to expand (+), collapse (-) or hide (x) the timeline.
Our collection is continually updated, meaning some objects have missing details. Find out more
