A Pocket Program (in the UK a ReadMe) is a convention publication aimed to provide its members with an accurate listing of the program and other events of a convention in an easily portable form. It includes convention policy and general information, even details of local restaurants, when they are not in a separate guide.
Because a pocket program must be printed at the last minute (the program continues to change right up to the convention as program participants drop in or out of the program) it is usually typeset simply and printed cheaply. Later changes are notified using newsletters, pink sheets or even mobile phone apps.
The ReadMe name comes from Eat Me and Drink Me in Lewis Carroll.
