This study guide should start with an explanation of what I mean by filing systems. Whether one is referring to the filing of records on a shelf or the filing order of papers within a record, both are filing systems and both are organised differently. To cover filing systems in a comprehensive way, therefore, we not only have to discuss both of these systems but also the numbering and organisation of records or papers that allow them to be filed and retrieved. Drawing on examples from the health service, this study guide will cover the following topics: • numbering systems • filing within a record • methods of filing • filing of a record within a filing system • tracing records within the filing system It is important to emphasise the importance of a well organised and maintained filing systems without which many businesses and organisations could not function efficiently.
