My goal is for my document to have a standard article documentclass to use the pages for an essay setting, but at the end I need to include newspaper articles and would like to format the latter pages as two columns for these newspaper articles. Does anyone have a suggestion as to how I should approach this? Tables are not reasonable for obvious reasons and I am not sure what other tools are at my disposal.
So generally I would like to format my document as
(Two Column Start)
(Two Column End)
Can I force all of the remainder into the left column only instead of having it balance? Also can I increase the space between the columns slightly?
