Written in the late 20th or early 21st century, the Dalek Survival Guide was a handbook produced to be the most comprehensive guide to the Daleks assembled since Earth was first alerted to their threat with Terry Nation's discovery of the Dalek Chronicles. It also served the purpose of equipping its reader with the necessary information in the event of an invasion.
The guide was collated from a variety of sources including research notes, scientific reports and recently disclosed classified papers. Despite its provenance, the guide also contained large amounts of material from future time periods thanks to the delivery of a battered Gladstone bag which, when emptied, was found to contain many more papers and documents than could have possibly fitted inside.
