In 2013, the Pacific Historical Review published a retrospective special issue on the writing of Chicana/o history, 40 years after the publication initially produced such an edition. As Albert Camarillo noted (2013, p. 504), Chicana/o historiography had undergone a transformation in its coverage, depth, and conceptualization. Since 2000, publishers have a produced a growing number of works on Chicanas/os as interdisciplinary research across different scholarly fields have encompassed historical concerns that have added to the mounting archive relevant to Chicana/o history. Particular mention should be made regarding the increase of research related to gender and sexuality. Indeed, a standard database search found over 4,000 citations under the rubric of “Chicano/Mexican American history” for the years between 2000 and 2016. But, the field is not without significant gaps, challenged by questions of periodization, interpretation, and integration into larger narrative historical schemes. Nevertheless, these problematic aspects have also led to provocative insights, fruitful debates, and productive conceptual explorations.
