What content is included in the different EBSCO Discovery Service Source Types?

Source Types are facets that simplify or expand search results within EDS. When you conduct a search, you will see Source Types in the left-hand column of your result list. When an institution’s catalog items are loaded during EDS set-up, Publication Types “roll up,” or are assigned, to Source Types. Please see the chart below for these assignments.

Publication Types are limiters that allow a user to search specific classifications of publications, such as periodicals, newspapers, or books. Publication Types are assigned to records in a database. Publication Type is searchable by the field tag PT (phrase indexed).

Although Source Types combine Publication Types, they are not directly searchable. And since Source Types are made up of multiple Publication Types, a specific record may appear under both.
