Thesauri come in all forms. Some, like PubMed, are in the form of a hierarchy tree and it is easy to see which are the broader (more general) and the narrower (more specific) terms. Other, like in EBSCO, put the terms in a list and label them "broader" and "narrower". Some, as with many ProQuest databases, include both options. Terms are seldom the same across thesauri as each thesaurus focuses on the materials within its own database.
