That's how the question was phrased in an English quiz I just took. The correct answer was 'yes'. Maybe the wording makes a difference, because the Purdue OWL has several example book citations with no mention of the author unless it's an anthology.
For all works in a research paper you should give credit to authors (unless the requested format of citations does not include the author heading).
On the source your provided, there are many examples where they included the author, or the author "company". If there are so many authors that they would take up ample space in the resources/citation section of the research paper, you can write the first author along with "et al" after to designate there are more authors (again, this is dependent on the citation style).
MLA in particular requests: Last Name, First Name. Title of Book. Publisher, Publication Date.
