Classified! A Confidential 3-D Dossier (anthology)

'Classified! A Confidential 3-D Dossier' was an anthology of in-universe-styled dossiers on the Ninth Doctor and his adventures as first depicted in series one of Doctor Who. The anthology was written by Stephen Cole and published by BBC Children's Books on 27 October 2005.

The anthology explicity justified the summarisation of the plots of the first series of Doctor Who as in-universe data retrieval, captured as composite pictures taken by spy-cams, which in turn justifed the inclusion of 3D glasses with the book as "special glasses", in-universe. Notably, this anthology was also bookended by in-universe messages from Doctor Who Magazine character Muriel Frost, who also made a cameo in Aliens of London — where she also died — but this anthology was set a year prior, in 2005.
