This collection, which dates from the early 1900s to 2010, includes hundreds of postcards collected by various donors. The postcards provide important visual information about many elements of the City of Hudson. They provide images of architecture and various types of buildings. Also, they contain a wide range of illustrations (drawings and photographic images) on subjects as varied as urbanization, transportation, industrialization, education, health structures, events, and the environment. The collection features postcards from a multitude of publishers, based mostly in New York State. Some of these postcards have been used for correspondence which gives us insights into the subject depicted on the postcards as well as into the lives of the residents. This collection is a valuable resource for researchers. Even though some postcards have suffered from inadequate storage conditions or poor paper quality, the vast majority of the collection is in fair/good condition and may be handled with appropriate precautions.
