Comparison and research limits

Historical source-health measurements were not collected for every record. Changes in the tracked office set and archive depth make raw month-to-month growth unsuitable as a trend. For a comparison, restrict downloads to the intersection of offices with accepted publications in both periods, and report excluded sources and missing dates. Current retrieval health is available on the coverage dashboard.
