MEETUPS application usage guide
Browse biographies

Select Biographies from the menu on the left to browse the full list of musical biographies stored within MEETUPS. The filter option in the top tight can be used to narrow your selection.

View meetups within single biographies

Selecting an individual biography will display further details on the biography. A full list of meetups extracted from the biography are available to explore, along with summaries of the most frequent participants, places and themes that occur within the meetups.

Explore all meetups via a search interface

Selecting Explore from the menu on the left offers a search interface for exploring the full database of meetups. If you are interested in meetups that occurred in a particular place or involved a particular participant, the search fields provided offer this functionality.

View in tabular or map form

As well as exploring your search results in tabular form, the Map tab at the top of the page can be used to give an alternative visualisation of your search results. The map offers familiar pan and zoom controls. Clicking on individual map points will give an overview of the meetup that has been recorded at that location.
