How to add citation for a whole paragraph? If I write a report and a whole paragraph is based on one source but not cited verbally it seems unnecessary to include the reference after every sentence:

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua (source 1). Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat (source 1).

Now I found a Phd thesis that puts the reference after the last dot of the paragraph to indicate that it is based on this very source:

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. (source 1)

Is this a common practice? Is it generally understood? What are other ways to add the reference for a whole paragraph?
Generally it is sufficient to cite each source only once in each place where you refer to material from this source. "Place" may be one sentence, one paragraph, one definition, etc.

If you cite a paragraph verbatim from another source, put it in quotation marks or in a quotation block and add one reference to the source at the end.

If you have a whole paragraph referring to one source but don't actually quote it, it gets a little bit more tricky. You have to make sure that a reader clearly understands that the whole paragraph is based on the source you are citing. A simple citation in parenthesis just added at the end of the last sentence may not be sufficient to make this clear. One way to cite in this case is to write something like "The following argument is based on (source)" at the beginning of the paragraph in question.
