 Now look at the second bit of the quote from Chicago , <unk> separated from the preceding sentence by a demure three @-@ point <unk> .

" ) occurs on page <unk> , which is no less than 590 pages later than the material before the <unk> , in a section titled " <unk> Taken from Secondary Sources . " Here 's the full quote , with what Dershowitz left out set in bold : " ' <unk> in ' . To cite a source from a secondary source ( " quoted in " ) is generally to be discouraged , since authors are expected to have examined the works they cite . If an original source is unavailable , however , both the original and the secondary source must be listed . "
