Besides their "Family Jewels", the CIA also recently released lots of other interesting documents, which can be searched through at their FOIA Electronic Reading Room. While some are questioning their heavy use of redaction, if you read the context of the redacted text carefully many secrets can be gleaned.
For instance, consider the document titled "Agency Hosts Movie Premiere and Sneak Preview". It recounts a screening at CIA Headquarters in Langley, VA of the made-for-cable movie "In the Company of Spies", which was filmed on location there. Although they obviously want to keep it on the hush-hush, the keen-eyed will notice that the document redactedly intimates at a highly classified CIA gift shop:
Redactions also hint at a secret CIA house band, whose name is only known to the upper echelon of the Intelligence community:
Given the fevered redacting at the end suggested by the crescendo of multiple, overlapping white boxes, one can only assume that George Tenet's drum solo must have really kicked [EXPLETIVE DELETED].
(Note that the line right before that contains a redaction joke by Tim Matheson. Perhaps the Publications Review Board redactor has a sense of humor.)
