A curated digital archive of over 700 auction catalogues documenting national and international auctions of Indian modern and contemporary art from 1987 to the present. The archive serves as a research tool for scholars, curators, students, and practitioners engaged in the study of Indian art auctions and their market histories. Auction catalogues are not merely commercial records; they are critical materials that reflect how artistic value is constructed, circulated, and historicised. They offer insight into curatorial strategies, pricing practices, and shifts in aesthetic and institutional priorities. As material artefacts, catalogues trace the changing reception of artists and artworks, the emergence of collectors and collections, and the evolving infrastructure of the art market. By consolidating these documents, Book.Auc supports longitudinal study of Indian art's engagement with global and regional markets. It invites close reading of the catalogue as a form both textual and visual that mediates between art history, commerce, and cultural memory.
