One of the BEST features about HubPages is that the copyright remains with the original author.
The majority of other writing sites on the Internet automatically own an author's material once submitted ~ it's in the fine print when you sign up on other sites.
HubPages, the only site I trust, fully respects the copyright of the original author.
As such, original work published on HubPages remains the property of the author and can be passed along to heirs of an estate.
Similarly, any quotes or excerpts or photos or links in a Hub (always used with credit, of course) remain under the copyright of their original creators.
No one can legally take/use/assume/put someone else's work into a Hub and copyright it for themselves.
A copyright always remains with the original creator. (Unless sold as "work for hire" or given away by contract as with most other Internet sites.)
