SPARC is pleased to join with PLOS and OASPA in releasing an update to the popular HowOpenIsIt? Open Access Spectrum (OAS) guide.

This resource outlines the core components of open access (e.g., reader rights, reuse rights, copyrights, author posting rights, etc.) across the continuum from “open access” to “restricted access”.

DECLARING INDEPENDENCE was published in 2001 by SPARC (the Scholarly Publishing & Academic Resources Coalition) and TRLN (the Triangle Research Libraries Network), partners in bringing this initiative to the research community.
