A day in the life could involve:
- Managing Digital Assets: Organizing and creating access systems for a company's vast digital files, images, and videos.
- Conducting Research: Performing deep-dive research for law firms, medical researchers, or corporate strategy teams.
- Curating Collections: Building and maintaining specialized collections for museums, academic institutions, or historical archives.

- Community Engagement: Developing programs and resources for the public in a city or county library system.
Average lowest mls salary Salary
To understand your potential, it’s best to start with the national benchmarks. According to the most recent data from the U.S. Bureau of Labor Statistics (BLS), the median annual wage for librarians and library media specialists was $64,370 in May 2023.
However, a median figure only tells part of the story. The BLS provides a more detailed picture of the salary range:
- Lowest 10%: Earned less than $40,990
- Median (50%): Earned $64,370
- Highest 10%: Earned more than $103,530
Salary aggregator Salary.com reports a similar median salary for a Librarian I (entry-level) at around $65,040, with a typical range falling between $56,922 and $74,013. This data confirms that while starting salaries can be modest, there is significant room for financial growth throughout your career. The key is understanding what drives that growth.
Key Factors That Influence Salary
Your final salary is not determined by a single number but is a composite of several critical factors. Strategically positioning yourself in these areas can have a dramatic impact on your lifetime earnings.
###
Level of Education
The MLS or MLIS is the standard, essential credential for most professional librarian and archivist positions. However, additional education can unlock elite, higher-paying roles. A Ph.D. in Library and Information Science is often required for tenure-track faculty positions at universities or for directing major academic research libraries, roles that command significantly higher salaries.
Furthermore, a dual-master's degree can be a powerful salary booster. Pairing an MLS with a Juris Doctor (JD) is common for high-paying law librarian positions. An MLS combined with an MBA can lead to lucrative roles in corporate information management or competitive intelligence.
###
Years of Experience
Like most professions, experience is a primary driver of salary growth. Your career earnings will typically follow a clear trajectory.
- Entry-Level (0-3 years): Professionals in their first few years can expect salaries in the lower end of the range, typically $45,000 to $58,000. The focus here is on gaining foundational skills and proving your value.
- Mid-Career (4-10 years): With a solid track record, you can move into specialist or management roles. Salaries often climb into the $60,000 to $85,000 range as you take on more complex projects and leadership responsibilities.
- Senior/Director-Level (10+ years): Top-level professionals who direct library systems, manage corporate information centers, or serve as senior archivists can earn $90,000+, with many six-figure salaries found in specialized, high-impact environments.
###
Geographic Location
Where you work matters—a lot. Salaries are often adjusted for the local cost of living and demand. According to BLS data, the top-paying states for librarians are:
- District of Columbia: $94,000 (mean wage)
- California: $88,610
- Washington: $83,780
- Maryland: $81,390
- New York: $77,540
Conversely, states with a lower cost of living, such as Oklahoma, Mississippi, and West Virginia, report the lowest average salaries. When evaluating a job offer, always consider the salary in the context of local housing, taxes, and other expenses.
###
Company Type
The type of institution you work for is one of the single biggest determinants of your salary. The funding models and perceived value of information services vary drastically between sectors.
- Public Libraries: Often funded by local taxes, these roles typically fall in the lower-to-median salary range.
- School (K-12) Libraries: Salaries are usually tied to teacher pay scales within the school district.
- Academic Libraries (Colleges & Universities): These positions generally pay more than public libraries and offer strong benefits packages. Salaries rise with the size and prestige of the institution.
- Federal Government: The federal government is a top employer, with high-paying roles at institutions like the Library of Congress, the National Archives, and intelligence agencies.
- Corporate/Special Libraries: This is often the most lucrative sector. Law firms, medical corporations, financial institutions, and tech companies hire information specialists to manage proprietary data and conduct competitive research, and they pay a premium for this expertise. Salaries in this sector regularly reach the highest end of the pay scale.
###
Area of Specialization
In the information economy, specialization equals value. Developing expertise in a high-demand niche is the most effective way to maximize your earning potential.
- Law Librarianship: Requires deep knowledge of legal research databases and sources. Often requires or prefers a JD alongside the MLS.
- Medical or Health Sciences Librarianship: Involves managing clinical research, patient data, and pharmaceutical information.
- Digital Asset Management (DAM) & Data Curation: A rapidly growing field focused on organizing, preserving, and providing access to large-scale digital information for corporations and research institutions.
- Competitive Intelligence: A corporate role focused on researching competitors and market trends to inform business strategy.
- Archives and Special Collections: Involves working with rare and unique materials, often requiring specialized knowledge in preservation and history.
Roles in DAM, competitive intelligence, and law librarianship are consistently among the highest-paid in the field.
Job Outlook
The BLS projects that employment for librarians and library media specialists will grow by 1 percent from 2022 to 2032, which is slower than the average for all occupations.
However, this figure can be misleading. While traditional librarian roles may see limited growth, the demand for professionals who can manage digital information is strong. The skills learned in an MLIS program—data organization, information architecture, research, and metadata creation—are more valuable than ever. Job seekers who focus on high-growth specializations like data curation, digital asset management, and user experience (UX) research will find themselves in a much stronger position.
Conclusion
An MLS degree is a powerful and versatile credential that opens doors to a rewarding career. While the "lowest MLS salary" may be a concern for prospective students, it's crucial to see it as a starting point, not a destination.
Your earning potential is not set in stone; it is something you actively build. By making strategic choices about your specialization, industry, and location, and by committing to lifelong learning and skill development, you can steer your career from the entry-level range toward the six-figure salaries earned by top information experts. The future belongs to those who can master information, and an MLS is your first step toward that mastery.
