I recently discovered that Camden County NJ has constructed the CORA - Camden Online Records Access. The interment records for New Camden Cemetery are on there, only searchable by year. http://carma.ci.camden.nj.us/dswv/
(Input "cemetery" AND the desired year under the Words and Phrases input fields).
For anyone who is familiar with that area of Camden, this is a HUGE help since the cemetery is a ward of the state and the records are only available through the historical society.
