Electronic Archiving

IJAU ensures the long-term preservation of, and permanent access to, all published content through the following mechanisms:

• LOCKSS and CLOCKSS. The journal uses the LOCKSS and CLOCKSS systems to create a distributed archiving system among participating libraries, which may keep permanent copies for preservation and restoration. The LOCKSS manifest is available at this page.
• PKP Preservation Network (PKP PN) [cek]. The journal content is deposited in the PKP Preservation Network, a private LOCKSS network operated by the Public Knowledge Project.
• Crossref DOI. Every article has a Digital Object Identifier (prefix 10.32734) registered with Crossref. The DOI provides a persistent link to the article.
• Article metadata and full texts are indexed in Garuda, the national scientific repository of the Ministry of Higher Education, Science, and Technology.
• Institutional backup. The journal website and its database are hosted on servers of Universitas Sumatera Utara and are backed up regularly by the university's IT unit [cek].

Authors may also deposit the published version of their articles in institutional or subject repositories, in line with the journal's Copyright and License policy.
