Know Your Enemy was a series of informational "fact files" about various enemies encountered by the Doctor. The series originated as part of the Unit Hotline feature in early issues of Doctor Who Weekly, the first being released with issue 26.
In the 21st century, the feature was continued in a handful of revival Doctor Who annuals. Doctor Who The Official Annual 2016 renamed the series Black Archive, though the content remained the same. The original name returned in the 2021 annual.
