A little about the problem.
Users of library catalogs know what to expect
Archives/Manuscripts are more mysterious
?One box?Ten boxes?
Need to drill down to full record to find out quantity of materials
Or examine the finding aid

Visualization
Multi-value attributes datasetWe propose an innovative method for visualization and exploration of items associated with multi-value attributes
Item 1 A B
Ex) Multi-value attributes dataset
Item 2 A C E
Item 3 B
Item 4 D E
Items Multi-value attributes
Item 5 B D E F
In our application, items are collections, and multi-value attributes are subjects.
How to visualize this type of dataset?
Aggregation and Overlap

• Intersection (overlap) carry relations between attribute values and help users to explore dataset
• Selected attribute values are in users’ interest.• Focusing on the overlap with selected items

Visualizing total amount on selected attribute values and overlaps at the same time.Giving users an idea for further adding selected attribute values for searching items.
In our application, sizes of collections are used instead of number of items.

Next Steps• Stage ArchivesZ online with small dataset and
invite the larger archives and historian community to give feedback
Thank you!• Special thank you to Jennie Levine, Curator of
Historical Manuscripts University of Maryland Libraries – provider of EAD encoded finding aids and answers to many questions
