8. Advantages and disadvantages of indirect sources

Indirect Data
Pros Cons
Takes less time to gather than original (direct) data. You may not know exactly where the data came from and so it may be unreliable
It may be cheaper to obtain than gathering original data If you have to buy the data from a specialist company then it may be more expensive that collecting it yourself.
Makes extra use of original data you already have by processing for a different purpose There may be only a small part of the data needed so you have to extract what you want from a large data set.
Archiving ensures that all the data you have collected is available for uses you have not considered just yet. You may not be able to obtain exactly the data you want.
