A microfilm reader is a device used to view images stored on microfilm, which is a film containing miniature photographs of documents. These readers project the images onto a screen, allowing users to read and examine documents that would otherwise be too large or fragile to handle. Microfilm is often used in libraries and archives to preserve historical records and newspapers. Microfilm readers come in various types, including manual and digital models. Some advanced readers can convert microfilm images into digital files, making it easier to store and share information. They are essential tools for researchers, historians, and anyone needing access to archived materials, such as libraries and museums.
