Thanks very much for your help and recommendation; however, I am still having a bit of difficulty. I followed your instructions for the Set Up steps 1.1 and 4.3; however, you say that I need to assign the suffix uncgtr as the public identifier for the item. I do not see anywhere to do that in steps 1.1 or 4.3; however, as you note, when I get to the table of contents for future issues, a box for “public id” does appear for each article. A problem arises, however, because I can input uncgtr for the first article, but after that, I cannot add the same suffix to the rest of the articles. Once uncgtr is saved as the public id for any article, OJS will not let me use it again for any other article. Apparently in the table of contents, OJS does not allow me to use any public id more than once. Also, if I publish an issue with just one article using the uncgtr as the public id, no DOI shows up for that article when it is published. I am obviously not doing something correct, so any suggestions on trying something else for this would be greatly appreciated. One other question, you suggest upgrading to OJS 2.4.2. If this would help solve my problem, I will gladly suggest that to our IT folks; however, before I do that, would upgrading cause any problems with the data and journals that we are currently supporting? If upgrading takes a lot of effort on the part of our IT folks, they may not be agreeable to my plea. Again, Thanks for the help you have given, and Thanks for any other suggestions you might have for my problem.
