Lifetime Genealogist wants to 'give away' a lifetime of family records

How do I respond to a person who has a trove of genealogy material from all over the world? This person apparently wants to 'clean house' by getting rid of a lifetime collection?

I am certain the Family Search Library has very strict parameters regarding accepting private contributions.

I am fairly well versed in research and documentation in my own family records going back to my possession of 3 temple record books from Denmark, Norway and Sweden originated in the 1910's but not sure how to evaluate information from others.

I staff the Walla Walla Washington family search center once a week. I am going to involve the director in evaluating this unknown material. Any other directives?
