Hi--I'm not sure where is the best place to direct my question, so I hope you can send it to the right place. When I write master gardening columns for our local paper, I always cite the URL, article titles, and author(s), if those are given. Do I need any further permission to use extension information? For example, I use a photo credit line if the photographer is identified; otherwise, I write, "Photo from the University of Maryland Extension Office."
