When is the Main Library open on Sundays?

The Main Library is open every Sunday from 1-5 PM, except Sundays in July and August. None of the branches have Sunday hours.

Where else does my library card work? Where are these libraries and what are their hours?

When was the Main Library built and who designed it?

The original Richardsonian Romanesque Main Library was designed by Van Brunt and Howe and opened in 1889.  In November 2009 the new glass addition, designed by award winner William Rawn Associates, opened to great acclaim.  In addition, the original Van Brunt building was superbly renovated by Ann Beha and Associates.  To learn more about the library's history and the design process for the new Main Library, please follow this link.

What are the "green" aspects of the new Main Library?

Your new green Cambridge Public Library has been Silver LEED (Leadership in Energy and Environmental Design) certified by the United States Green Building Council.

Here are just some of the initiatives:

  • The Children's Room and Teen Room contain bamboo floors, which was chosen specifically for its sustainability. Bamboo is a grass and not a tree, which means it grows fast and plentiful. Often, growth occurs as quickly as three to five years.
  • The old open parking lot was replaced with an underground garage. By putting the parking underground, we had room for a large landscaped and wonderful new children’s play area. In fact we could say we created a  ‘green roof’ for our garage!
  • Many of the windows that you see in the new building do open. The entire front of the new addition is a double skin curtain-wall which is like a giant insulated window helping to warm us in the winter and cool us in the summer.
  • A day-lighting system has sensors to turn off lights when there is enough light from the sun. There are occupancy sensors in all small rooms that turn off lights when they are unoccupied.
  • Products used contain no volatile organic compounds (VOCs) commonly found in floor and carpet glues.
  • The library uses low water flush toilets and sinks with automatic sensors.
  • The building contractor recycled 96% of our construction waste. Materials such as wood crates, paper, building materials and old stone were set aside for re-use.
  • There is a 350,000 gallon underground water tank by the front entrance that is used to catch storm water runoff from a portion of the city. The tank is part of a large MWRA project to control run–off and reduce localized flooding.

Does the Main Library have parking?

The new Main Library has a 70-car underground parking garage with access from Broadway that is open when the library is open. It costs 25 cents for every 12 minutes of parking.

The parking machines accept quarters and Mastercard or Visa.

Does the library have places where I could hold a meeting or have study sessions?

The Main Library has four meeting rooms that are available for Cambridge-based not-for-profit community groups.

There is other meeting room space available at the Central Square and O'Neill branches.

Are there any jobs at the library? How can I apply for one?

Job opportunities are posted on our employment site when available.

Do you have a Friends of the Library organization I can join?

Does the library have computers for internet and/or word processing?

All Cambridge Public libraries have free wireless access and all branches have computers with internet access.

Does the library offer passes to local museums?

What does the library offer for tax forms and tax assistance?

Every year the Cambridge Public Library provides both state tax forms, and a wide range of the most common federal tax forms and publications.  Massachusetts tax forms can also be downloaded via the Massachusetts Department of Revenue webpage. Federal forms not available at the library can be downloaded via the Internal Revenue Service webpage. Tax forms from most other states can also be downloaded.

The Cambridge Public Library offers tax assistance courtesy of the Harvard Law School TaxHelp Program.  This program usually runs during the months of February, March and April. Over the years, students from Harvard Law School have helped hundreds of library users prepare their tax returns.  Although this service is open to all, the primary aim of this free program is to help the disadvantaged, the elderly, and those new to this country.  Individuals with complex tax filings or unique tax issues will be advised to seek professional tax assistance.

Does the library offer ESL classes? What ESL-type materials do you have?

The Literacy Project housed at the Central Square Branch has many great resources and services for people looking to learn or improve their english.

Monthly delivery service is available for patrons who are homebound due to short or long term disability.  This service is for Cambridge residents only and must be scheduled.

For more information or to arrange for this service please contact Janet Borron at 617-349-4035 or

What databases are available in the library? How about from home?

Through various funding sources the library has access to over 56 databases, many of them accessible from home.

Can I get a book from outside the Minuteman Network? What is inter-library loan?

If a title is not available in the Minuteman Library Network, you can request it through the Commonwealth Catalog. The Commonwealth Catalog is another way to access materials in participating regions of Massachusetts. You must login using a valid library card and pin.

If the item is not available through the Commonwealth Catalog and is more than 12 months old, it may be requested through Interlibrary Loan (ILL). ILL provides access to the holdings of public and academic libraries throughout the continental United States. The purpose of this service is to strengthen the depth of offerings available to individuals who want to explore a topic in greater detail than the scope of the Cambridge Public Library or the Minuteman Network collections can support. ILL is neither intended to nor can it replace access to the research facilities of an academic system.

You may request ILL materials in person or online. You may have one request active at a given time. Materials can take 3-6 weeks to arrive. We will send you an email when your title arrives.


Does the library have a public fax machine?

No.  None of the seven library locations has a public fax machine.  You should try your nearest copy center.

What magazines and newspapers does the library own?

The Cambridge Public Library system has over 800 magazine and newspaper titles for your perusal.  Check this list to see if we have what you are looking for.

Does the library accept book donations?

The library accepts very specific and select items as donations.  Please view our policy.  We've provided a list of agencies in the area that do accept more expansive donations.

Does the library have WiFi?
