Public libraries in the United States are not one national system. They are thousands of locally governed agencies, and our directory lists 4,878 of them across 49 states. A library in Abilene, Texas follows different rules from one in Albany, New York, or Alsea, Oregon, even though all three lend books and offer free internet access. Knowing who runs a library tells you who sets its card policy, who pays for its hours, and who to call when something goes wrong.

Who Runs Libraries in the United States: Federal, State, County and City

Cities, counties and special districts run most public libraries. The federal government supports the system from a distance, and state agencies sit in between. Here is how the layers fit together.

The federal role is support, not operation

There is no federal public library that issues cards to the general public. The Library of Congress serves Congress and researchers, and the National Archives and Records Administration operates the presidential libraries. The Institute of Museum and Library Services sends Library Services and Technology Act money to each state library agency, which passes it on as grants. The Government Publishing Office's Federal Depository Library Program places government publications in more than a thousand libraries, where anyone can read them free.

State library agencies set standards and share resources

Every state has a state library agency. Examples include the California State Library, the Texas State Library and Archives Commission, the Massachusetts Board of Library Commissioners and the Indiana State Library. These agencies administer state aid, run statewide database programs, collect annual statistics and, in some states, certify librarians. They rarely handle complaints about a single branch. They do keep the official list of library systems, which helps if you cannot tell which one serves your address.

City, county and regional libraries deliver the service

Your card comes from a local library. Single-community libraries are common in the Northeast and Midwest. Abilene Public Library on Cedar Street, Allentown Public Library on Hamilton Street in Lehigh County, Albany Public Library on Washington Avenue and Abington Public Library in Plymouth County, Massachusetts each serve one city or town.

County libraries cover wider areas. Lenawee County Library in Adrian, Michigan, Adams County Library on North Cedar Street in Adams, and Washington County Public Library in Abingdon, Virginia work this way. New Jersey leans heavily on county systems, and the Atlantic County Library System in Absecon is one. Regional systems combine several counties. Great River Regional Library in Minnesota, Aberdeen Timberland Library in Washington state and Southern Peaks Public Library in Alamosa, Colorado are examples.

Legal structure varies even among libraries that look alike from the street. Some are municipal departments, some are independent districts with their own boards, and some are nonprofit associations that contract with a town. Louisiana uses parishes instead of counties, so the Livingston Parish Library's Albany-Springfield Branch is a parish service even though some data sets label it a county.

Specialized libraries serve narrower audiences

School libraries answer to school districts, and college libraries answer to their institutions. Law libraries form another group. The Akron Law Library Association on South High Street in Summit County, Ohio, and the Maryland State Law Library in Annapolis support courts, lawyers and the public. Their collections center on statutes, case law and legal forms rather than bestsellers.

How Rules, Fees and Services Differ Between States

Each library board sets its own policies, so the same task can be easy in one town and awkward in the next. Four areas cause the most confusion.

Card eligibility. Most libraries issue free cards to anyone who lives, owns property or pays taxes inside the service area. Some also accept people who work or attend school there. People outside the area may be offered a paid nonresident card, and the price is set locally, so ask the library before you assume anything.

Fines and fees. A growing number of systems have stopped charging daily late fines on regular items. Many still bill for lost or damaged materials, and some charge for printing, copying and meeting rooms. The governing board decides, not the state.

Digital access. Many libraries lend e-books and audiobooks through apps such as Libby or Hoopla. Which apps you get, and how many checkouts you are allowed each month, depends on what your library or its regional consortium has paid for.

Sharing between libraries. Interlibrary loan lets your library borrow an item from another system for you. Some states run statewide delivery networks, while others rely on regional consortia. Wait times and fees vary, so ask at the desk.

When you apply for a card, bring the following:

  • A government-issued photo ID, such as a driver's license or state ID
  • Proof of your current address, such as a recent utility bill, lease or piece of mail
  • A parent or guardian, for most applicants under 18, since the age limit differs by library
  • Your existing card number, if you are asking about borrowing at a neighboring library
  • An email address, which most libraries need to set up digital access

If you have just moved, staff can often accept a second document, so ask before you leave.

Choosing the Right State Page for Your United States Library Search

Start with the state, because state law decides how library districts are created, how they are funded and which agency oversees them. Libraries in Ohio has the most listings in our database, with 273. Libraries in Wisconsin and Libraries in Michigan follow closely, and both states have many small-town and county libraries that run independently. Libraries in New Jersey shows the county-system model at work.

Then narrow to your city or county. If you are unsure where your address falls, check your property tax bill or your county's website. Library service areas sometimes follow township or school district lines rather than city limits.

These mistakes come up often:

  • Searching only by city name. Albany has libraries in New York, Minnesota, Missouri and Louisiana. Akron has a law library in Ohio and a Carnegie public library in Fulton County, Indiana.
  • Assuming a card works next door. A card from one system is not automatically valid in the next town.
  • Calling the wrong level. Your state library agency cannot waive a fine at your local branch.
  • Skipping the hours check. Small-town libraries may open only a few days a week.

Use the state pages below the introduction to see every listing for your area, then phone the library to confirm its current rules.

Finding Libraries in the United States Through Our Directory

Our database holds 4,878 library listings in 49 states. Each entry gives a street address, county and phone number, so you can confirm details before you travel. The records cover more than neighborhood branches. They include city libraries such as Abilene Public Library in Taylor County, Texas, county systems such as Lenawee County Library in Adrian, Michigan, and regional networks such as Southern Peaks Public Library in Alamosa, Colorado.

Read each entry with the governing body in mind. The Shasta Public Library Anderson Branch on West Center Street in Anderson is a branch of a larger library, so ask whether one card covers every location. Ash Fork Public Library in Yavapai County, Arizona, and Ackley Public Library in Hardin County, Iowa, show how small towns run their own libraries, often with limited hours. If you are searching in a large market, try Libraries in California or Libraries in Texas, then narrow down to your city.

Phone before a first visit. Hours change by season, and a listing cannot tell you about a closure for repairs. The questions below cover what people ask most.

Frequently asked questions about libraries in the United States

Mostly local government. Cities, towns, counties and special library districts operate the great majority of public libraries, and local taxes provide most of their funding. States add aid, shared databases and standards through a state library agency such as the Indiana State Library or the California State Library. The federal government contributes mainly through Library Services and Technology Act grants, which the Institute of Museum and Library Services sends to state agencies. For a problem with a card, a fine or a building, start with the local library's director or board.

Usually yes, but the definition is wider than your street address. Most libraries issue free cards to people who live, own property or pay taxes in the service area, and many also accept workers and students. Some systems cover several counties with one card, as Great River Regional Library does in Minnesota. If you live outside the area, ask about a nonresident card, which often carries an annual fee set by that library's board. Bring photo ID and proof of address, and ask staff to confirm your address falls inside the boundary.

It depends on the library. Many systems have stopped charging daily late fines on most books and movies, often to remove a barrier for families. Others still charge them, and almost every library bills for items that are lost or damaged. Short-loan items such as laptops or mobile hotspots may carry stricter penalties. Check the fees page on your library's website or ask at the desk, because the policy is set by that library's governing board, not by the state or the federal government.

Bring a government-issued photo ID and something showing your current address, such as a utility bill, lease or recent mail. If your ID shows an old address, staff can often accept a second document. Children usually need a parent or guardian to sign the application, and the age at which a teen can apply alone differs by library. Have an email address ready, since most libraries use it for digital access and notices. Some let you start an online application and finish it in person.

Not automatically. A local library or system issues each card, so a card from Albany Public Library in New York is not a general pass to libraries elsewhere. Some neighboring libraries have reciprocal agreements, and several states run statewide borrowing programs, but these usually stop at the state line unless nearby libraries have agreed otherwise. Visitors can often read, use computers and attend programs in a public library, sometimes with a guest pass. If you are moving, register at your new library once you have proof of the new address.

Start with your county or municipal website, which usually names the library your taxes support. Your property tax bill may include a library levy line, a clue to the district. State library agencies also publish directories of systems. In states where district libraries are common, boundaries may follow township or school district lines rather than city limits. Call the nearest branch with your address. Staff can usually tell you within a minute whether you qualify for a free resident card and where your closest location is.

Many law libraries welcome the public for legal research, though access rules differ. The Akron Law Library Association on South High Street in Akron, Ohio, and the Maryland State Law Library in Annapolis are both in our listings. Call ahead to confirm hours, visitor policies and any membership requirements. Staff can usually show you where to find statutes, court rules and legal forms, but they cannot give legal advice or tell you how to handle your case. For advice, contact a licensed attorney or a legal aid organization in your state.
