I am planning to use Public Domain Content as free reports. This public domain material publication that I found from a Government website says that the content can be republished and redistributed.
1. There are a few images that I like in the publication and want to use them in my reports. So can I along with the content use the images as well for the free reports?
2. I don't intend to change the content as it is great as it is. Now I know if you are using Public Domain content as it is you cannot copyright it. But can I still use it as a supplement to my main product without mentioning the source?
