FamilySearch Labs (part of the LDS) is taking volunteers as a part of their Historical Records and Images project. Currently they have placed records at the test site, some indexed and some not indexed for those chosen to be a volunteer tester. Each tester is asked to use the records and report the ease of use and/or any technical problems. They are specifically wanting to know how easy it is the find un-indexed records.
I signed up as a volunteer last week and received my acceptance email over the weekend. If you are chosen as a volunteer, you will have access to images such as the 1900 U.S. Census, WWII Draft Registration Cards, Ohio Death Certificates 1908-1953 and Utah Death Certificates 1904-1956 – some of which are partially or fully indexed.
To volunteer, go the following page: Historic Records and Images Project
Good luck – I hope you get chosen!
