My inbox had a message from Reclaim the Records (https://www.reclaimtherecords.org/) today: there is now an online index of New Jersey death records from 2001 to 2017. There are also digital images available from 1901-2000, although there are gaps from 1904-1920 and from 1930-1948. The index is free and searchable, the images are browsable. Here is the link: The New Jersey Death Index
That's great news! Thank you for sharing!
