The use of books varies by discipline in college-level research. In the humanities, scholarly books reporting on original research that is too lengthy to fit into a single journal article are an important part of the scholarly record. They are often published by academic presses and go through a peer-review process. Here, books and journal articles serve the same research function, and there are many important original studies that you will miss if you only look for journal articles as sources.
In the sciences, almost all original research is published in journal articles. Scholarly books provide authoritative overviews and introductions to topics, as well as setting standards for some fields. These books are acceptable sources for some college level assignments, but you should not substitute a book if your professor asks for a scholarly article.
The social sciences use books for both of the functions described above, and you will need to evaluate your book and your assignment to see if it meets the requirements.
