When you have a practical problem on which you want information, it is not always necessary to do it the hard way, that is, to gather data empirically. It may well be that someone has already encountered a similar problem and perhaps has found an effective solution to it. If it has been documented in a book or in an article, you may find the document by means of a reference search.
Even when you cannot find the complete solution to your problem in earlier documents, these often contain useful data related to your problem, like the following:
facts, statistics and research findings,
raw data to be processed in new research. These may reveal attitudes, ways of life, products used at different times, etc. Such information is often found in private documents like letters and memoirs.
