When your assignment calls for academic sources, that means you are to use academic (scholarly, peer reviewed) books or complete academic (scholarly, peer reviewed) journal articles. An abstract to an article is not acceptable as a source. Your must read and use the ENTIRE article.
Even though you find them in academic databases along with journal articles, a book review is not an acceptable academic source for a research paper. The database will indicate "review" or "book review" somewhere in the record.
