Comma uses based on sentence order
Follow an introductory word, phrase or clause with a comma
Set off sentence interrupters (middle of the sentence) with commas
Interrupters also include words like “no” and names
Commas before and after interrupters tell readers that the information not only

“Series” refers to a list of words of the same sort

you don’t use a comma.
Don’t overuse commas
Over-using commas slows readers down.
Commas in the wrong places signal readers about a possible sentence structure that

elements, you really can’t go wrong if you use a commas with the “and”.
We do not use a comma with “and” to connect any two items with one major exception: If
you are connecting two sentences that could otherwise stand alone as complete
sentences, use a comma when you use one of these seven combining words – but, or,
yet, for, and, nor, so.
Other connecting words, like however, moreover, and therefore, fall into a different
category that conventionally calls for a semicolon when these words connect what would
otherwise be two sentences. Labeling and Crediting Visual Images
Unless a visual occurs solely to provide a text break and emotional tone, provide a
caption with each visual. In the caption, tell readers what the image represents and
point to the features you want readers to pay attention to.
Unless the image is your own (i.e., you took the photograph or composed the
graph/chart/image), provide a credit notation that attributes the image to the copyright
When one person contributes all the photographs in a text
