Series numbers are assigned to collections as they are accessioned into the Westchester County Archives. As a result, series that come from the same county department (a Record Group), or that relate to the same subject often do not have consecutive series numbers.  

Therefore, these Series Number Listings are most useful if the Series Number is already known.  Scrolling or browsing through them to find records is not really necessary, given the Records by Department, Records by Subject, and Records by Chronological Order options of viewing the collections.

To use the series number listings, the series names are listed in numerical order and have been broken up into pages consisting of 50 series’ names each. To view the series names, click on one of the series ranges listed on the right. Then click on a series number to view the corresponding description.
