This is a great little book giving you an clear and concise overview of which episodes of the classic Doctor Who television series from the 1960s are missing (currently 97 in total).
Unfortunately, the BBC wiped the original production videotapes of many early Doctor Who serials. While some have been recovered over the years, many are currently still lost. This is a brief guide outlining which episodes are still extant (i.e. exist in the BBC archives) and which are still missing.
