We have a few prison guides here to read. There is also a guide written by the partner’s of some people who went to prison recently.
Please be aware that all guides are based on personal experience: everyone is different and all prisons and guards are different.
These guides are also available to download from the following places:
LDMG and GBC guide
Partners Guide to Prisons
HMP Survival Guide
If you need these guides sent to you by post just email a postal address to email@example.com
