Here's a link to my original post about these columns.
For the ones I have, the breakdown by year is as follows:
1967: 21 1968: 18 1969: 28 1970: 22 1971: 21 1972: 18 1973: 14
I have multiple copies of some columns, mostly labeled in my Mom's handwriting, as if she bought several papers so that she could distribute the columns to friends and family. A few don't have visible dates, and some have no titles.
I think I'll try my hand at posting these columns on a weekly basis (more-or-less), which would take me something like three years to complete if I did all the ones I have. If I can, I'll provide both the original column and a transcription.
Here is a chronological list. For the columns without dates, I've estimated the date based on other clues such as printing format (which changed several times during the six years) and articles on the obverse side of the page.

I'll use this list as the central link for the columns, updating it so that each title will link to the location where I've posted the column.
