I need to cite in a bibliography, using CMS 15th ed, two articles that have been serialized. The first was published in one journal/newsletter over three issues and another in a journal in two parts. Can someone please point me to an example in the CMS on how to cite this because I have been unable to find this case in the CMS? Is it three entries and two, or one for each but listing the multiple numbers of the journals? I would be most grateful for any help here.
