I do not have much of a concern in protecting my blog (I have a greater concern in financially benefitting from it). The idea that someone could copy-paste a post to his/her blog without my knowledge or consent--especially if it appears to be a fraudulent website--does concern me, but it does not keep me up at night, though.
Recently, however, I have completed a tremendously long post. It consists primarily of links to newspaper articles. However, I have put in some unique effort to it and provided names and locations, often requiring additional research. I shall have a similar post next year and, I suspect, it shall be even longer.
I would like to claim ownership of what I have done in providing and arranging all that information. If I can do this then how? Or because I get the information from online news articles and Internet websites (primarily Wikipedia and TimeAndDate) am I allowed to seek protection of my work?
