I would to see elaborations in the captions of all three images, albeit in different ways. Images 1 and 2: what are the places? What are their histories? Where did you find them in the archive? (Same goes for the images of Biddy Mason, which seem to be different photographs of her.) Image 3: where is this archive? What is your relationship with it?
The caption for Image #2 is fully realized.
The caption for Image #1 is brief and direct. It is dependent on the larger essay for full meaning. The caption raises questions for me. It presents the image as a starting point, an invitation to an archive. When I look at the image, I see florescent lighting, long, dark narrow aisles and an excess of boxes--closed, sorted, infused with meaning--to be investigated. Perhaps, for an archivist this is an idyllic place, but I sense a toxic environment present in this image. I realize a different, deeper, meaning of toxic is invoked in this essay, still I think it would support the analysis further if the starting place for our understanding of archive is also made more nuanced.
