Observation of records
- One type of observation focuses on the physical traces left by the factors of interest.
- These traces are of two types;
1. Accretions left
2. Erosion

- • Accretions involve a trash to eliminate the liquor consumption in cities without liquor stores.
- • Erosion observations are less frequent. An example would be the study of a relative readership of different sections of an encyclopedia by measuring the wear and tear on the pages.

- • The records of previous activities such as population census are physical traces of previous periods.
