This document discusses opportunities and challenges of using open source software like Open Journal Systems (OJS) and Open Conference Systems (OCS) in academic libraries. OJS is used to manage journal workflows from manuscript submission to publication, while OCS manages conference workflows. OJS supports over 11,500 journals in 16 languages and is maintained by the Public Knowledge Project in partnership with other institutions. The document outlines benefits of OJS like being free, online-ready, enabling social media integration and standardizing/automating journal management processes. It also discusses opportunities for academic libraries to use OJS to address challenges from declining print readership and increasing needs for online access and impact evaluation.
