Particular concerns exist about the ability to access and read digital records over time, since the rapid pace of change in technology can make the software used to create the records obsolete, leaving the records unreadable. A considerable amount of research is being undertaken to address this, under the heading of digital preservation. The Public Record Office Victoria (PROV) located in Melbourne, Australia published the Victorian Electronic Records Strategy (VERS) which includes a standard for the preservation, long-term storage and access to permanent electronic records. The VERS standard has been adopted by all Victorian Government departments. A digital archive has been established by PROV to enable the general public to access permanent records. Archives New Zealand is also setting up a digital archive.
