How to Research at the RAC

Anyone can conduct research at the RAC. If we have archival materials that can be useful to your research topic, you are welcome here.

Because of limited seating capacity, researchers need an appointment in order to conduct in-person research in the RAC’s Reading Room. Contact the RAC Reference team at to make your appointment.

You will also need to create a researcher account in RACcess, our online request and duplication management system.

Get started on your research by searching our online finding aid catalog DIMES.

As with our archival materials, Library materials are non-circulating and are only available in the RAC’s reading rooms.

When We’re Open

The RAC is currently only operating one Reading Room, with limited seating capacity, which is open Monday through Friday from 10:00 am to 5:00 pm, except for designated holidays.

Inclement weather can sometimes require the RAC to close for the safety of our staff and researchers. During the winter, if ice or snow is predicted for suburban New York, it is advisable to telephone the RAC at (914) 366-6300. A recording noting a closure or delayed opening is generally posted by 7:30 a.m. If you have a scheduled research appointment, we will also do our best to email you with as much advanced notice of the closure as possible.


Since the RAC is not located near restaurants or stores, we encourage researchers to bring their own lunches. We have a researcher lounge with a refrigerator and microwave. We also provide assorted cold beverages as well as tea and coffee. WiFi is available throughout the RAC.

How to Get to the RAC

By Car

The RAC is located at 15 Dayton Avenue, Sleepy Hollow, New York 10591.

By Train from New York City

The RAC is easily accessible by train from Grand Central Terminal in New York City to Tarrytown on the Metro-North Hudson Line. If you’ve made prior arrangements with the Reference team, the RAC will provide transportation to and from RAC for the following trains:

  • Departs Grand Central 9:00 a.m. Arrives Tarrytown 9:46 a.m.
  • Departs Tarrytown 5:42 p.m. (Car Service leaves RAC at 5:15 p.m.) Arrives Grand Central 6:42 p.m

The train schedule may be subject to change, so be sure to check the Metro-North web site to verify departure times. If you come on a different train or miss the RAC shuttle van, there is a taxi stand at the Tarrytown station.

Before Your Visit

Within the week prior to your visit, we’ll need to schedule a virtual orientation. An archivist will be in touch about scheduling a virtual orientation (one-on-one) which should not take more than 30 minutes. We’ll review the reading room policies and procedures and get you ready to work in the reading room, and if you would like, we can chat further about your project and the archival collections.

What You Can Expect When You Get Here

When you arrive on the first day of your scheduled research visit, you will be greeted and brought up to the reading room.

We’re an archive of important historical materials, so we do have a few simple rules that we ask all researchers to follow when they’re in the RAC’s Reading Room:

  • Place your outerwear, bags, and other nonessential items in the lockers provided.
  • Use only pencils and laptops for notes. No pens.
  • Food, beverages, and chewing gum are not permitted.
  • Review one folder at a time and mark its place in the box with the OUT card provided
  • Items in folders should not be rearranged or removed.
  • Avoid placing other items on top of documents. Ask the desk monitor for book weights.
  • If metal fasteners need to be removed, ask the desk monitor for assistance.

Our Reading Room can be cool at times, so be sure and bring a sweater. Generally speaking, you may use a digital camera or your phone or tablet to photograph collection materials for research and educational purposes. However, the desk monitors may place some restrictions on your photography if the archival materials being handled are fragile or in poor condition.

The RAC has several microfilm reader-scanners available in our Reading Room which enable researchers to print or to save images from microfilm onto flash drives. We encourage you to bring your own flash drive if you anticipate using microfilm during your visit.
