Thanks to Reclaim the Records, the Nebraska Death Index (1904-1968) is now available to everyone online. Even better, access is available free of charge.
“In May 2019, citing Nebraska’s Public Records Law, Reclaim The Records made a request for “a copy of the Nebraska Death Index and/or finding aid to deaths, from its onset to 1968”. You can read the whole request on our website (PDF), if you want, because we like making all our correspondence and court cases public.”
