Digital Archiving

To guarantee long-term digital preservation, permanent accessibility, and uninterrupted scholarly availability of all published scientific assets, the journal under Universitas Ahmad Dahlan implements a multi-tiered archival strategy:

1. PKP Preservation Network (PKP-PN):
The journal participates in the PKP Preservation Network, utilizing the LOCKSS (Lots of Copies Keep Stuff Safe) program to digitally preserve decentralized permanent archives across global library nodes.

2. Institutional Repository of Universitas Ahmad Dahlan:
All published issues and individual article galleys (PDF and metadata) are permanently deposited in the institutional digital repository of Universitas Ahmad Dahlan (Repository UAD).

3. National Scientific Repositories:
Full metadata and articles are systematically harvested and indexed into the Indonesian national scientific portal, GARUDA (Garba Rujukan Digital) and Indonesia OneSearch (IOS) by the National Library of Indonesia.

4. Self-Archiving Policy:
Authors are permitted and encouraged to deposit the published version (Publisher's PDF) in non-commercial institutional or thematic repositories immediately upon online publication with proper bibliographic attribution.
