The Browse catalogue function allows you to enter a catalogue at the very top level and then work your way down, so that you can see how the archive is structured, and how each item is related to each other.

Worked example

As an example, we will use CRO Cambridge's collection 23. 

• Click on Browse catalogue in the left hand menu. You will see all our catalogues arranged alphabetically by title. Scroll down to find "Cambridge Anitquarian Society", or click Ctrl and F to search for it directly.
• Click on the adjacent number 23 to open up the Collection level record. You will see that this collection comprises two series, 23/1 and 23/2.
• If you now click on 23/1, the Series level record for that series opens, showing us that this series is comprised of glass lantern slides. Moreover, you can see that the series is made up of three sub-series: 23/1/1, 23/1/2, and 23/1/3.
• We can burrow our way further down the catalogue, if we like. If we click on 23/1/1 (slides of Cambridgeshire parishes) and then 23/1/1/1 (slides of Great Abington) we eventually reach all the items in that folder.
