Data explorer
Filter the collection and every summary below re-aggregates against the same slice. With all filters cleared, the totals here equal the Overview exactly — that agreement is checked by a test in the repository, and it is what keeps this page a view of the analysis rather than a second, competing one.
Distributions under this filter
Four views of the current slice. Each redraws as the filter changes; each has a table twin behind the Table button.
Datasets per subcollection
Deposits per year
Harvested datasets carry no publication date and are absent from this chart.
Top keywords
Top authors
Descriptor labels such as Federal Agency are removed before counting.
Stratified summary
The same slice, grouped by any of the stratifiers. Rows count each dataset once per group it belongs to, so a dataset with four keywords appears in four keyword rows; the totals therefore exceed the dataset count for any multi-valued stratifier.
