Advancing the Systematic Study of Legacy Archival Classification Frameworks The Institute for Microfiche Indexing Standardization Studies (IMISS) is dedicated to the rigorous examination, preservation, and comparative analysis of pre-digital indexing methodologies, with a particular emphasis on microfiche-based municipal records management systems. Our work focuses on the structural, procedural, and taxonomic foundations that governed information retrieval in administrative environments prior to the widespread adoption of digital databases.
