Social Work Perspectives in the Library is written by Antonia Bruno, Excelsior Service Fellow for the NYS Library in the Office of Cultural Education.
What is Systems Theory?
Systems Theory suggests that behavior derives from factors that work together to form an individual’s system. An individual’s system consists of the varying levels of support and interaction one has with others and the overarching environment surrounding them. Simply put, we are products of the relationships we hold with others, the connections we hold with our local communities, and broader society. Our behavior is not created in a vacuum but instead influenced by our system.
This theory provides multiple explanations for human behavior and experiences. It also permits various perspectives depending on whether a holistic view of an individual’s system is accounted for or contrastingly; specific levels are the focus in perspective-taking.
Additionally, this theory helps clinicians and direct service providers map out the multiple factors that influence an individual's behaviors, mindsets, and life outcomes. There are a few social work perspectives that derive from Systems Theory, including the Ecological Systems Model, Person-in-Environment Perspective, and Family Systems Theory.
The Ecological Systems Model created by psychologist Urie Bronfenbrenner in 1979 is often used to describe how children develop over time and how their internal, external, and environmental supports lead to outcomes as they age. Later, I will provide a breakdown of the Ecological Systems Model with examples of interactions within and between the levels in an individual’s system.
Clinicians and direct service providers who apply Systems Theory when conducting biopsychosocial assessments benefit from gaining a holistic view of the client outside of the medical model that defines the biopsychosocial assessment. A biopsychosocial assessment dives into a client’s history and current behaviors, including their biological, psychological, and social factors which help a provider understand the client’s thoughts, feelings, and behaviors. The medical model can be restrictive when assessing clients and creating treatment plans because it is outlined by a client’s biology and psychology and doesn’t provide a holistic view on its own. When this assessment is paired with the Systems Theory, a more detailed focus on a client’s social relationships and connections to broader society is accounted for in treatment plans and goal-setting. To understand an individual’s social factors means to dive into the types of support and social safety net the individual is afforded.
Ecological Systems Model
The social factors live within a multitiered ecosystem of different types. These are called the microsystem, mesosystem, exosystem, macrosystem, and chronosystem, as defined by Urie Bronfenbrenner.
Microsystem
Includes the relationships and environments individuals interact with directly including work, school, family, friends, and neighbors. This type of system has a bidirectional influence meaning that the individual may be influenced by the factors in this system but also have the ability to influence factors within the system.
Example: A child in school will be impacted by their educators in school but also has the power to impact the educator with how they interact with their peers in the classroom.
Mesosystem
Includes the different elements within the microsystem that interact with each other and impact the individual’s experience.
Example: An individual’s family member starts working at the same job as the individual’s spouse, which will impact the individual’s relationship with both parties.
Exosystem
Includes the elements in an individual’s life they do not directly interact with but which still impact their behavior and outcomes.
Examples: Mass media, local government, and social services.
Macrosystem
Includes the social norms, culture, and political system surrounding the individual. The macrosystem holds broader societal implications. These overarching norms and political systems may impact the individual’s view of themselves and others they may closely identify with.
Example: An individual suppresses the expression of their identity because of the social norms in their local community prohibiting that identity.
Chronosystem/Time
Focuses on the unavoidable changes that occur over an individual’s lifetime. Such changes that occur over an individual’s lifetime can present the individual with a transitional period marked by necessary adjustment.
Example: Historical events, aging, experiencing grief and loss, and death.
How Does This Impact Your Role as a Library Worker?
Systems Theory provides library workers with a framework to map out the larger systems that influence their communities. With an understanding of the systems and various factors that influence patrons, library workers are better informed to serve vulnerable patrons with empathy and understanding. Most have a general understanding how an individual’s inner circle influences their opportunities and outcomes. But we can look to the Ecological Systems Model which provides a larger context of factors that influence behavior outside of our microsystem.
The public library may reside somewhere between the macrosystem and the exosystem levels of the model. The library can positively impact outcomes for community members:
- Positive health outcomes, such as free blood pressure kits/screening, chair yoga, providing health related materials, food pantries on site
- Positive education outcomes, including tutoring and homework programming for youth, free professional test-prep materials for adults, free textbooks related to college or trade school course work
- Positive employment outcomes, like career counseling sessions, Microsoft and related tools workshops, resume and job application assistance
These are just a few ways that libraries connect their communities with resources that increase wellbeing and provide access to varying types of care. Moving beyond programming and services within the library, libraries can influence an individual’s outcomes by committing to a culture of care that supports varying needs seen in the community. This can be done through outreach with relevant community partners to bridge gaps in service acquisition. This can also be done by embodying practices reflective of a trauma-informed approach, aiming to be a positive influence in a patron’s system.
Reflect:
- Think about the many factors that make up your personal systems. What areas impact you the most?
- Think about your library’s services. Are there areas for improvement or exploration in the way that your library impacts patrons’ systems? How can the library uplift and enhance its role in a patron’s personal support?


























In the Office of Cultural Education's newest This is How We Do It video, NYS Museum staff explain the story of a Revolutionary War gunship found buried under the World Trade Center site in New York City and demonstrate the painstaking process of rebuilding this incredible relic.
If you’ll excuse the pun, this story has a lot to dig into, and that’s exactly what we did! NYS Library collections are rich in Revolutionary War narratives, and we provisioned some of our favorites for this journey aboard the Museum’s gunship.
Waterways and the Revolution
Archaeologists discovered the buried gunship while excavating the World Trade Center site in 2010. Based on the ship’s remains, researchers were able to determine that it was likely built near Philadelphia in the early 1770s for the purposes of patrolling shallow waterways like New York's many harbors and rivers.
Much of the early fighting in the Revolution took place around Manhattan and Long Island. A 1976 publication from the New York State American Revolution Bicentennial Commission, Long Island in the American Revolution, describes how the conflict played out for the inhabitants of Long Island. The publication’s foreword seems to suggest that Long Island was particularly impacted by the machinations of the Revolution:
However, much of the patriots’ maritime activity around Long Island made use not of gunships, but of whaleboats (although some were fitted with guns). Thirty feet long and pointed at both ends, Long Island whaleboats could be handled by only a few oarsmen, who could also carry the boats on their shoulders over land. Guerilla-style “whaleboat warfare” saw patriots in New England cross the Long Island Sound to kidnap loyalists, but was primarily focused on efforts to disrupt British supply routes:
Loyalist and British forces occasionally used whaleboats, but as the book says, “the rebels were the clear masters of whaleboat warfare” (p. 44). You can read Long Island in the American Revolution in the Library’s Digital Collections.
Chains Across the Hudson
British forces were constantly trying to take control of the Hudson River during the Revolution. In response, Continental forces under George Washington endeavored to strategically block the river by running an enormous chain across it. Multiple chains were attempted, the most famous of which is the chain that stretched across the river from Constitution Island to West Point and figured in Benedict Arnold’s great unmaking.
According to the book History of the Great Iron Chain, Laid Across the Hudson River at West Point in 1778, the Sterling Iron Works won the contract to forge the chain. Each link was over two feet long and weighed 300 pounds. The entirety of the chain weighed 165 tons. According to the book, “a greater part of the chain now lies at the bottom of the Hudson.” But not all parts—in 1858, the NYS Library received the gift of three links from the chain. The links were presented by General Franklin Townsend of Albany. His great-grandfather, Peter Townsend, was one of the proprietors of the Sterling Iron Works. You can find History of the Great Iron Chain in the Library's Digital Collections, as well.
The Revolution in Lower Manhattan
New York City during the Revolution was still a long way from becoming the bustling metropolis of today or even a hundred years ago. However, many of its most important Revolutionary landmarks still stand.
A map from Landmarks of the American Revolution in New York State, another digitized publication of the Bicentennial Commission, shows a landmark found in Lower Manhattan not far from the World Trade Center site. Fraunces Tavern was the location of many important New York moments of the Revolution, including General Washington’s 1783 farewell to the officers of the Continental Army.
The map from page 4, drawn in thick, simple strokes that capture Lower Manhattan below Canal Street, shows the location of Fraunces Tavern just a few blocks east of Bowling Green and several blocks southeast of the World Trade Center site. The locations on the map are surrounded by the marks of New York City’s growth, such as the West Side Highway, the Brooklyn Bridge, and the Brooklyn-Battery Tunnel (now the Hugh L. Carey tunnel). Today, Fraunces Tavern serves as a high-end restaurant with a museum on an upper floor.
Dress to Impress
More than 600 pieces of timber and 2,000 artifacts—including musket balls, buttons, and ceramic tankards—were recovered from the gunship site. A small military button bearing the number “52” found with the wreckage pointed researchers to the likelihood that the ship was at one point captured by the 52nd Regiment of Foot, a British force that saw action in Boston, Philadelphia, and New York.
We have several resources at the NYS Library that provide detailed information about the uniforms of various fighting forces in the American Revolution. Titles like Uniforms of the American, British, French, and German armies in the War of the American Revolution, 1775-1783 (call number 355.14 L49a) and Soldiers of the American Revolution: a sketchbook (call number 973.34 fU587 76-38241) provide detailed pictorial information on these details.
Most notably, the NYS Library has book of illustrations dedicated to British military dress, A Representation of the Clothing of His Majesty's Household and of all the Forces upon the Establishments of Great Britain and Ireland from 1742. The Library’s copy was previously owned by George Washington, who received it as a gift in 1787. This item is part of the NYS Library’s George Washington Collection.
(We’d also like to add that sword enthusiasts may enjoy The American sword, 1775-1945; a survey of the swords worn by the uniformed forces of the United States from the Revolution to the close of World War II.)
