We recognize the valid concerns of authors, readers, librarians, and others regarding the need for long-term preservation and access to scholarly research as publishing moves into the online era. Our journal archiving and preservation policy includes the following measures:
Our electronic content (website, articles, manuscripts, etc.) is stored on two sources. Content on one server is online and accessible to the readers. The copy of the same content is kept as a backup on offline resource.
All journal issues are abstracted and indexed by several abstracting and indexing services, which store much essential information about the articles.
IJE allows authors to deposit their original version and published final version/PDF in an institutional repository and non-commercial subject-based repositories or to publish it on the author's personal website and departmental website (including social networking sites, such as ResearchGate, Academia.edu, etc.), at any time after publication in the journal in compliance with the Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0). Publisher copyright and source must be acknowledged, and a link must be made to the article's DOI.
All journal issues are deposited to the National Library of Indonesia – the legal deposit library of Indonesia. The copies of the articles are available to the scientific community through their system as an alternative to the journal's own.
