It is required by MLA, APA & Chicago styles (notes/bibliography) to know precisely what information is found from another source. Citations also help to distinguish your words and thoughts from others. So, while it might feel awkward to write and read a paragraph with a citation at the end of every sentence, it is necessary.
An end-of-paragraph citation does not meet the standards of most citation styles. In most cases, a citation is required (either in-text or as a superscript number/footnote) for every sentence that contains information from a source.
Exception for Chicago:
An exception to this is when using the Chicago Author/Date style; please check with your professor first to determine if this style is accepted. If permitted, please see the link below.
Exception for APA:
APA also does permit one citation to be used at the beginning of a paragraph and not be repeated as long as it is evident that all additional sentences continue the paraphrase. Using words like; Additionally, Furthermore Moreover, Also, etc., might help convey this but be careful as it must be clear you are referring to the same source.
