I'm not sure what the real purpose of your project is. Just looking at the link I can't say for sure... Apparently you're trying to build a digital library, with public access.
If that's the case, you might want to look for DSPACE, or similar software for institutional repositories.
If what you want is a web portal, you might want to check out some CMS like Mambo or Xoops.
But if your interest is in Electronic Publishing of Scientific Journals, then stick with OJS for it provides all the control of the editorial process, but, more importantly, it provides free access to information with tools for readers to have context of their reading.
