Information collected and synthesized from existing data and sources
Secondary research establishes what has been done and what hasn’t, identifying opportunity gaps to help suggest a research direction and methods.
It is sometimes referred to as desk research, in contrast to primary research conducted as fieldwork or empirical research.
Sources may include books, research papers, journal articles, and conference papers, records and statistics, or any number of other archives.
In design, research might include precedent projects, products or documented case studies, photographs, maps, diagrams, and other visual support records.
It is traditionally summarized in systematic reviews or literature reviews, with full citations of sources.
In design, secondary research can also be collected into visual summaries or blogs, for shared viewing, sorting, synthesis, and the crafting of narratives.
The WorldCat database allows users to search the collections and services of more than 10,000 libraries worldwide, including the option to select specific media types.
