Put together a quick flow chart on how to avoid plagiarism! Please correct me if I'm wrong on the outside sourcing issue, I wasn't quite sure what to put there.
UPDATES
from Day Glo: For outside sourcing, "just include the URL of the source in the description of the RECord, if it's something you found online."
from LilacAmy11: "Not just any outside sourcing is ok, whether you include the URL or not. Anything that is public domain, however, is free to use as much as you'd like. It's important that the piece specifically states public domain or is not subject to copyright laws (most everything made before 1923, but it's important to check)."
from via: Not everything on archive.com is public domain, for more information on what is public domain check http://www.hitrecord.org/records/90476.
