This guide is not intended to present a set of rules or procedures which must be followed. Instead offers ideas and techniques which can be consulted as a kind of 'toolbox' by staff working in the field. The methods described can be applied or adapted to various situations requiring information on the refugee population. The methodology presented in the guide is supported by a number of related measures: lists containing standardized supplies detailed in Part 5, availability of a roster of resource persons to assist in planning registration exercises in the field, training and a registration database.
