The Archive Catalogue for the Royal College of Psychiatrists includes two entries for the Defeat Depression Campaign. The first is this archive of 5 boxes of material with “access by appointment only” [The College has been asked many times, over many years, if it might make this “educational material” available online, but has declined to do so]:
The second entry is a “Signed contract between the RCPsych and Wendy Lloyd Audio Productions” and is again“access by appointment only” and with any reproduction “subject to the College Archives Preservation Policy.”
