Due to a rise in COVID cases, masks are required when visiting the Library building.

Bloomberg Terminal

The Bloomberg Terminal, which tracks real-time financial market data, is an invaluable financial tool whether you are a job seeker looking for openings or an aspiring investor. The Terminal is open to all patrons. Darien residents, people who work in Darien, and Friends may reserve the Terminal in advance. Just stop by the Reference Desk on the Second Level to reserve your spot. Or call 203-669-5236 or email us.

Meeting Rooms

Darien Library is equipped with nine private meeting rooms which may be reserved online. There are three large rooms which may be rented for your business meetings. Small meeting rooms are available for two hour blocks of time and may be reserved by Darien residents, those who work full-time in Darien, and Friends at the $300 level. Some rooms can be reserved up to a month in advance and are available to non-residents on a first-come, first-served basis. Make your reservation

Database Access

Find information about businesses, financial data, career guidance, and industry journals through our Business and Investing databases. Our other research databases are useful for searching thousands of journals.

Research Assistance

Our reference librarians are experts in finding articles and data relevant to your business needs. From looking up elusive historical stock quotes to providing demographics for your business proposal, we can get you the information you need to meet your business goals. Just submit a Book-a-Librarian request to the Reference Desk with your query and we will set up an appointment to learn more about your project.


A Notary Public is available at Darien Library free of charge during most normal hours of operation. Notaries witness and verify the signing of important documents and administer oaths. You will need to bring two forms of ID containing your signature (e.g. valid driver license, passport, credit card), one which must also have your photo. Please do not sign the documents prior to appearing before the Notary Public.


Skip the line at the post office and mail your documents at the Library. You will pass the blue mailbox as you walk into the building from the parking lot. We sell stamps at the Welcome Desk.
