National Declassification Center (NDC) Quarterly Release Volume

SUMMARY

The National Declassification Center (NDC) periodically releases declassified documents from various military and civilian agencies. These releases are typically announced quarterly and consist of a list of declassification projects. Available data from several quarters indicates significant variability in the volume of pages released, with numbers ranging from hundreds of thousands to over four million pages per quarter. The number of 'declassification projects' or 'entries' also varies.

STRONGEST CASE FOR

The National Declassification Center is actively processing and releasing a substantial volume of historical documents, making millions of pages available for public research across different government agencies. The quarterly release schedule ensures a consistent flow of new material, even if the specific page count varies based on the nature and scope of the completed projects.

STRONGEST CASE AGAINST

While the NDC does release documents, the reported numbers of 'projects' or 'entries' can be misleading without a clear definition, and the page counts show extreme fluctuations, making it difficult to assess the actual average output or consistency of declassification efforts. The provided excerpts do not offer enough consistent data points to establish a reliable average quarterly volume.
