Some of the images in this collection are not labeled with a date or other identifying information. These images have been arranged into topical groups which mirror the groups used to organize the paper records portion of the Westinghouse Electric Corporation Collection (MSS 424). Within each topic, folders are arranged alphabetically.

For the majority of the images in this series the archivist has attempted to assign a very approximate date (e.g. - to the decade) and descriptive information using other materials in the collection, assistance from former Westinghouse Electric employees, or other research. In most cases, when a date is recorded as "c1900" or "c1930", it is meant to imply that the image might have been from those decades. Other images may have exact dates or closer estimates.

Topical groups are: Albums/Binders, Education, Employees (Individuals and Groups), Events, Facilities, Miscellaneous, Products, Publications, Radio Broadcasting, Research, and World War II.
