Hi bubbleboy,
I'm assuming you are referring to Journal Setup 3.5. OJS content is available via
OAI; all you have to do is provide an OAI metadata harvester with your journal's OAI base URL, and it will automatically harvest your journal's metadata -- that is, all the information about your published articles, including author information; title; abstract; date published; keywords; and so on. The articles themselves are *not* harvested, but OAI harvesters will typically include a link back to your journal for full-text access (subscription-protected, of course, if your journal uses subscription protection). For more information, see Kevin's article
Getting Found, Staying Found, Increasing Impact.
Cheers,
James
