The death and burial records are kept in the parish church books.
The Digitalarkivet web site has been adding scanned images of the original Norwegian parish church records for anyone with Internet access since November 2005.
The Digitalarkivet web site - http://digitalarkivet.uib.no/cgi-win/WebFront.exe?slag=vis&tekst=meldingar An English option is available by clicking on that word from either the left hand column or the blue link bar along the bottom of the homepage. The scanned images are available from the homepage link "Skanna kyrkjebøker" [Norwegian version]/"Digitised parish records" [English version] which is listed along the left hand column and from the blue banner of links along the top section of the homepage. After you've clicked on that link and a new main page has presented on the screen be sure and read the instructions that are available from the Digitalarkivet for navigating the scanned records. The instructions are available in Bokmål (official Norwegian), Nyorsk (Norwegian), Davvisámegiella (Saami), and English. Recommended basic reading are the "Startsiden" [Norwegian version]/"Main page" [English version], "Brukerveiledning" [Norwegian version]/"User's guide" [English version] and "Om tjenesten" [Norwegian version]/"About this service" [English version].
Good information about translating the formats of Norwegian parish church records during various time periods, many of the basic terms used and understanding how to use the information should be studied at this web site - http://homepages.rootsweb.com/~norway/na20.html
There appear to be a few smaller databases of 'deaths' in Land areas that have been created - but they are NOT all inclusive. They cover only Torpa, Nordsinni og Østsinni sokn i Land prestegjeld 1847-1859; Nordre Land prestegjeld 1860-1871; and, Nordsinni sokn i Nordre Land prestegjeld 1882-1903 as are found on the Digitalarkivet website.
Only one of those three would be of interest to your search and it covers only 1882-1903. The only man with a given name starting with 'Eri' was a much much older man named Hansen.
So, if your man stayed in Nordre Land that leaves you the church records to pour through.
Norway has fantastic records available and the number of databases created by volunteers for even easier searching is unbelievable and increases all the time. But not everything is extracted into such electronic formats.
