I believe it was as well. It was considered to be copyright infringement, but the judge allowed fair use for the purpose that Google used it for. Which means, that it would be copyright infringement to do something similar, but you might be able to use the fair use defence if someone sued you. This means, however, that it will almost certainly go to court and you will have to retain a lawyer. So unless you have lots of money (and are willing to risk it), you shouldn't do something similar to what Google did.
