Electronic Archiving

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

• LOCKSS and CLOCKSS [cek]. The journal uses the LOCKSS system to create a distributed archiving system among participating libraries. 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.
• ISSN Portal. The journal is registered in the ISSN Portal under e-ISSN 3026-0477, which keeps a permanent bibliographic record of the journal.
• 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.
