USHMM Digital Collections Search
The United States Holocaust Memorial Museum sets the standard in Holocaust archives, and they are a pioneering force behind digitization. However, their service leaves much to be desired. The archives are hard to use and often not digitally available. Make sure that you scroll down and hit “Digital Availability” and select “Digitally Available” before searching. Also, “in English” is a helpful thing to check off when offered the opportunity.
USC Video History Archives
A great online resource that is free to use. Full-length testimonies of thousands of people available online, from home. You must make an account, if you want something less committal check out their youtube channel.
