Desk Research - is a form of research which applies a mix of quantitative & qualitative techniques, where the information is collected using secondary data (i.e. gathering and analyzing data which was already collected by another person or organization). Secondary data can be found from a variety of sources – the Internet, newsletters, company annual reports, newspapers, database searching, associations/trade bodies or by ad hoc personal contacts.
Desk Research offers a number of advantages:
It's a quick method of collecting information, Desk Research is easier than field research, secondary data is often ready to use and process. Open data from various state and non-state sources (statistical agencies, professional and expert organizations) are usually the main source of information for desk research. However, this method can have disadvantages: secondary data may not be recent, it might not be accurate and sometimes data is hard to find, depending on subject matter.
