YAD VASHEM's YOUTUBE STATION has a number of videos!
I've used their database. As it has been explained to me this database is ever expanding as volunteers type in information from testimonial pages. Please also know that these testimonial sheets are by memories. Therefore I have been told by at least one researcher that extensive interviewing and travel proved that memories were questionable.
It is riveting none the less to click till you get to a testimonial page that has a photograph of the person. And some of you may find family members in your heritage this way.
Also know that Yad Vashem has a database of Righteous Gentiles.
