EBSCO gives you access to title lists for our Bibliographic and Full-Text databases, via https://www.ebscohost.com/title-lists.
Certain database title lists include a column that distinguishes between core titles and priority titles. The difference between the two types of journals is:
Core Title - A core title is one that is included in its entirety in our database (cover to cover).
Priority Title - A priority title is one that contains certain information which is relevant to a particular database. In this instance we include only those articles that are relevant to the database instead of cover to cover content.
If the database title list does not include information on core versus priority titles, all journals in that database are core titles.
