Hey There
I would say if you think the content will be useful for your visitors/customers then add it. If you are wanting to add the content to attract new browsers through the SERPs then you are out of luck. As you say the content is not unique, so you are unlikely to be attributed as the source/original author of the content.
I don't think (although someone will come along and put me in my place) you will be penalised for adding the content, you just won't receive any SERP boost for it.
But as I say, if it helps your customers, then go ahead and add it.
