I am looking for all the nodes of the boundary of
the polygons.
I followed your instructions and it worked perfectly.
Thanks so much. Very helpful.
I obtained the XY figures:

and then started to follow this:
https://gis.stackexchange.com/questions/64535/how-to-convert-x-y-coordinates-to-longitude-latitude-using-quantumgis
to obtain the lat/longs. I selected 4326 as the CRS and
exported to a CSV. I did not do the calculator $x and
$y part, but it still produced the lat/longs. 2.37 million
features and it worked good. Very impressive.

So I am in a good place now. I plan to change the CRS to NAD27,
but I think I am good to go. I have a lot of work ahead of me.
I really appreciate your help.
Thank you Nyall.

Hi Mike!
First off, I'd strongly suggest upgrading to 2.18 (or 3.0, if you like
bleeding edge!). You'll get lots of bug fixes and improvement
behaviour over the older, unsupported 2.14 release. If you're stuck on
2.14 for some reason, you definitely should be running the final patch
release for that version, which is 2.14.22.
Do you mean for each node in the polygons, or just for the centroid?
The easiest way is to use the built-in Processing toolbox.
If you're after a lat/long for the centroid:
1. Run the "Polygon centroids" algorithm to obtain a point for each centroid
2. Run the "Export/Add geometry columns" algorithm to add a field for
centroid x/y values
3. Export to XLS/CSV/etc
If you're after a lat/long for each node:
1. Run the "Extract Nodes" algorithm to obtain a point for each node
2. Run the "Export/Add geometry columns" algorithm to add a field for
centroid x/y values
