Final Answer:
Databases that contain sources related to specific disciplines or topics are often referred to as subject-specific databases.
Step-by-step explanation:
Subject-specific databases are curated collections of information resources, including articles, journals, and other materials, that are focused on particular disciplines or topics. Unlike general databases, which cover a wide range of subjects, these databases cater to the specialized needs of researchers and scholars in specific fields. For instance, a subject-specific database might exclusively feature literature related to psychology, physics, or any other discipline. These databases offer more targeted and in-depth content, making them valuable tools for academic and research purposes. The term "subject-specific databases" accurately describes these resources that are tailored to the requirements of users seeking information within a particular academic or professional domain.
