I highly recommend these articles as a starting place if you are looking for information about any of these texts. They will make very good readings for classes, if you teach any of these gospels in your curriculum (whether university or church).
I plan to order hard copies of the journal for my personal library, but you can access this journal on-line. If your university has a subscription to the journal, you can print out a copy from your computer. If not, you can purchase individual articles on the website and print them from your computer.
My thanks to the editor, Paul Foster, who kindly sent me the details about the articles.
