Tags in research

A researcher may work with a large collection of items (e.g. press quotes, a bibliography, images) in digital form. If he/she wishes to associate each with a small number of themes (e.g. to chapters of a book, or to sub-themes of the overall subject), then a group of tags for these themes can be attached to each of the items in the larger collection. In this way free form classification allows the author to manage what would otherwise be unwieldy amounts of information. Commercial, and some free, computer applications are readily available to do this.
