Final answer:
A research database is more specific than a research search engine, as it provides access to peer-reviewed scholarly publications and is often subscription-based. Reference librarians can assist in navigating these databases effectively.
Step-by-step explanation:
One of the main differences between a research database and a research search engine is that a research database tends to be more specific than a research search engine. While research search engines may index a wide variety of sources and help in casting a broader net for information, research databases are often subscription-based services that provide access to a wealth of academic and professional publications, including indexed articles from specialized scholarly and technical journals. Hence, the answer to the student's question is E. A research database is more specific than a research search engine. This specificity usually translates into a more focused and refined search capability, offering peer-reviewed articles, conference proceedings, and other academically rigorous material.
A librarian or a reference librarian can be invaluable when navigating through the wealth of information available in databases, helping to refine search terms and providing guidance on the best research strategies. A general-interest database may serve as an excellent starting point for research, covering a multitude of topics across various sources. As research becomes more focused, subject databases become essential, providing comprehensive information related to specialized areas of study.
