For most of us, our first and primary use of Google Maps was to get directions. Google Maps has uncluttered the glove box in many automobiles, eliminating our dependence on road maps that are often outdated.
In addition to allowing you to be a consumer of maps, Google Maps allows you to be a creator of specialized maps.
One of the easiest tasks is to create a map that contains informational place markers. There are any number of reasons and contexts that motivate our placing markers on maps that we can share (or build together) with others.
To create a new map or to edit a map that already exists, please view these instructions.
Editing Google Maps
Below is a video that will walk you through a sample of how to add a pin in Google Maps.
Sharing Your Own Maps
Look for the 
link (upper left) on your Google Map page. The settings will provide you with a link that you can copy, paste and send to others, or you will have the option to invite people directly. To obtain the embed code and embed this map so that it shows up within the page of your blog or website, click on the 
menu next to the share icon.
