A treasury of impressions from England's past. Seals bear witness to history. Walter De Gray Birch's Catalogue of Seals in the Department of Manuscripts (Volume VI) presents a meticulous, scholarly inventory of a medieval seal collection found among British Museum manuscripts. Concise entries describe shape, legend and heraldic device; where known they note provenance and administrative context. The result is both an accessible historical seals reference for curious readers and a rigorous sigillography guide for academic researchers and museum professionals, equally useful to those studying medieval heraldry and those engaged in British archival research. Rooted in Victorian scholarship, Birch's careful documentation remains a cornerstone for anyone investigating Victorian era artifacts or the administrative life of England's historical documents. As a foundational sigillography handbook and a complete seals catalogue, it charts the visual language of authority - seals as tokens of identity, office and legal weight. For casual readers the catalogue rewards curiosity with a tangible sense of medieval practice; for classic-literature collectors it offers bibliographic heft and a slice of collecting history. Republished by Alpha Editions in a careful modern edition, this volume preserves the spirit of the original while making it effortless to enjoy today - a heritage title prepared for readers and collectors alike. Academic researchers and museum professionals will value the precise cross-references and typological clarity that support comparative study, while archivists and students of medieval heraldry study will find frequent points of entry for deeper inquiry. Detailed typologies and cross-referencing make the work a practical tool for comparative dating and attribution, aiding efforts to trace networks of power across medieval England. It rewards patient browsing as much as targeted research, and so appeals equally to the lover of antiquarian scholarship and to the collector assembling a library of England's documentary past. More than a reference, Birch's Volume VI is a bridge between archives and the public imagination - both a sigillography handbook and a humane record of how seals shaped governance, identity and memory.
