APERTURE CARD Meaning and
Definition
-
An aperture card refers to a type of standardized microfilm image storage medium consisting of a card-like structure with an aperture or window containing a microfilm strip. The card is typically made of strong durable material, such as cardboard or polyester, and measures about 7.37 x 3.25 inches (187 x 83 mm) in size.
The aperture or window on the card holds a microfilm strip, which contains microfilm images of documents, drawings, or other visual information. The microfilm strip is carefully aligned and mounted within the card, allowing only a portion of the strip to be visible through the aperture. This setup provides an organized and easy-to-manage format for storing and accessing microfilm records.
Aperture cards are widely used in various industries, particularly in engineering, architecture, and manufacturing fields. They serve as a reliable and compact storage solution for long-term preservation of documents and technical drawings. The cards are often labeled or indexed with relevant information, such as project names, part numbers, or document titles, making it easier to locate specific microfilm images.
To access the information stored on an aperture card, a microfilm reader or scanner is typically required. These devices allow users to view, enlarge, or print the microfilm images onto paper or digital formats, depending on the needs of the user.
Overall, aperture cards provide a convenient, space-saving, and durable method for maintaining and accessing microfilm records, ensuring the longevity and accessibility of important visual information.

Etymology of APERTURE CARD
The word "aperture card" combines two different etymological origins: "aperture" and "card".
1. "Aperture" originates from the Latin word "apertura", meaning "opening" or "hole". It entered Middle English through Old French and was first used in the 15th century.
2. "Card" comes from the Old French word "carte", which referred to a flat, stiff material. It can be traced back to the Latin word "charta", meaning "paper" or "papyrus". The term "card" has been used in English since the 14th century.
The combination of these two terms creates "aperture card" referring to a card or sheet of stiff material with an opening or hole, often used in microform technology for information storage and retrieval.
