The court uses CiteLinks, a program that scans documents for citations (when properly cited according to The Bluebook) and creates hyperlinks for court employees to Westlaw, Lexis, or other research providers.  The program also hyperlinks contemporaneously filed attachments  and previously filed documents in CM/ECF  when they are properly described during filing (click here for instructions).  Although it is not necessary to manually add hyperlinks to documents, CiteLinks will not alter/modify/change hyperlinks already provided by attorneys.
