The fair use privilege allows the public to make limited use of copyrighted works without obtaining permission from the copyright owners. One of the reasons for fair use is to encourage criticism and comment on copyrighted works. Quoting or excerpting a work in a review is a classic example of a fair use. Including a picture of a work you’re reviewing is also a good example of a fair use—this is done all the time in reviews. So long as you don’t use any more of the works involved than is necessary for your reviews, your intended use of works from the 1990s in your blog should qualify as a fair use. That said, not every copyright owner understands or agrees with the fair use rule, and some may complain even though your use is allowed by the copyright law.
