In order to manage the content of an e-journal, the formation of an editorial board is required. More than simply managing Peer Review, the Editorial Board is responsible for the overall direction and focus of the journal, and has much to consider in terms of publication, but also in terms of the day to day functioning of the e-journal.
Among other things, the responsibilities of the Editorial Board include:
Not all e-journals are peer-reviewed, but having a review process for your content is a way to ensure the continued and growing accreditation of your e-journal, and many repositories require Peer Review before inclusion in the repository is otherwise considered.
Open Journal Systems has a built in workflow for conducting Peer Review. The system provides template emails, manages due dates, and organizes blind or double-blind review depending on the needs of the e-journal.
Finding reviewers, however, is up to the editorial board of the e-journal. Managing your editorial decisions in a timely manner and following up with prospective authors and reviewers goes a long way in establishing the professionalism and academic seriousness of your e-journal.
There are a number of ways to find good reviewers for your e-journal;
Contact authors in your discipline - subject matter experts are very important to the peer review and editorial process, they can also ensure your content is vetted;
Inquire in topical centers and departments on campus;
Maintain relationships with previous authors to your e-journal - as it is possible that they have continued to develop themselves in the field.
