Citing vs Quoting
Quoting - using other words verbatim. (3 or more unusual words)
Citing - When you take someone elses idea. Or facts/info/methods. (facts that are not common knowledge to the audience you are writing to). You must cite if you summarize or paraphrase.
Difference between citing and footnotes/endnotes. Don't use for citation, use for parenthetical information.
... - when cutting out info from a quote .... when cutting out the end of the sentence. If ... is actually in the quote then use [...].
4 lines or more you use block quotes. (10 space indent)
Works Cited is only the works you cite... Bibliography is all the work you read.
