Prevailing citation practice in law journals is to use uniform resource locators (URLs) when citing electronic sources. Digital object identifiers (DOI) provide a more reliable and robust mechanism for citing digital, scholarly articles. This study examines to what extent DOI names exist but are not used in law journal citations. Citations to scholarly articles from twenty-five randomly-selected articles appearing in the 2007-2008 volumes of four major law journals (Harvard Law Review, Columbia Law Review, Yale Law Journal, and University of Pennsylvania Law Review) were checked for existing DOI names using CrossRef's Simple Text Query form. This resulted in 394 citations that could have had DOI names, but did not. This number suggests that law journal editors and librarians should consider adding DOI names to citations. For journals that publish exclusively online or are interdisciplinary, assigning DOI names to their own articles may be a prudent measure to better ensure long-term digital access and citation by scholars in other fields.
