Spectrum of Operational Research (SOR) is committed to the long-term preservation, accessibility, and availability of its published scholarly content.
All published articles and journal issues are made available through the journal's official website and form part of the journal's permanent scholarly record.
In addition to publication on the journal's official website, digital copies of published journal content are deposited and preserved in the Digital Repository of the National Library of Serbia .
Deposit in the Digital Repository of the National Library of Serbia provides an additional preservation and access channel for the journal's published scholarly content and contributes to the long-term availability of the scholarly record independently of the journal's primary website.
Published articles are assigned persistent identifiers, including Digital Object Identifiers (DOIs), where applicable. Authors and readers are encouraged to use the DOI as the persistent reference to the Version of Record.
Digital preservation by the journal is distinct from author self-archiving. Authors may also deposit permitted versions of their manuscripts in repositories and other scholarly dissemination services in accordance with the journal's Self-Archiving Policy .
Through journal-hosted access, external preservation, persistent identification, and author self-archiving, SOR seeks to support the continued accessibility and preservation of its published scholarly content.
