SPARC has announced the launch of the Open Access Spectrum Evaluation Tool. The tool provides a concrete way to analyze the openness of a particular journal. The tool measures journal policies regarding reading/reuse rights, author posting rights, machine readability, compliance with funder & institutional mandates, and other openness indicators.
Five hundred journals have been added to the tool to start and they hope to add another five hundred before the end of the year.
