Is reusing sources self-plagiarism? I have a class that I have to research a topic on. It can be anything and all I have to do is inform the class about the topic. It's not super intense research, just a small amount, enough for a 5 minute presentation. 

However, before, I had a research project that took up almost a whole school year about a topic we chose. It's a topic I'm interested in and I was wondering if it counts as self-plagiarism if I reuse sources from the old research project? Not all of them just a handful. It's almost all just facts and not much of my own analysis so would it be counted as plagiarism? 

Does turnitin count it as plagiarism if they find 2 papers using the same sources? The thing I'm concerned about is we have to do an annotated bib and I took the sources from an old annotated bib. However the info paragraph I basically rewrote it all and its a lot more simple than my old one, which has a lot of specifics. Also all the sources I am using are on my old annotated bib.
Yes, they will be flagged by Turnitin. However, why don't you just cite your own research? In that case, it's not plagiarism because you cite your own work correctly.
