Microfiche is a flat piece of film that contains miniature images of documents, typically used for storing large amounts of information in a compact format. Each microfiche can hold multiple pages of text or images, making it a space-saving solution for libraries, archives, and businesses. Users can view the content using a special reader that magnifies the images. This technology was widely used before the digital age, allowing for the preservation of historical records, newspapers, and other important documents. Microfiche is often associated with microfilm, which is similar but comes in a roll format, and both are part of the broader field of document preservation.
