Science & Engineering Librarian: Salary, Duties & Career Path
Explore real salary data by state and setting, core duties, required credentials, and how to advance as a STEM subject librarian.
Academic reference desks and corporate R&D teams both hire science librarians, but library pay scales tell two different stories. The Bureau of Labor Statistics reports a 2025 median wage of $68,270 for librarians and media collections specialists nationally, with STEM specialists routinely landing in the upper quartile and corporate researchers pushing well past six figures.
Demand is climbing alongside data-intensive research. Universities need liaisons who can teach citation management and data curation to graduate students, federal labs need cataloging and metadata librarians fluent in technical standards, and pharmaceutical and engineering firms need embedded searchers who can navigate patent databases and proprietary datasets. The tension for most candidates isn't whether the work exists, it's deciding which sector rewards their particular mix of library and information science training and STEM background.
A science and engineering librarian is a subject specialist who provides research support tailored specifically to STEM disciplines, from chemistry and biology to mechanical engineering and computer science. Unlike general academic librarians who cover broad collections across all subjects, these professionals bring deep knowledge of scientific literature, data practices, and technical information resources to their work.
Science and engineering librarians typically handle a range of specialized duties that set them apart from their generalist colleagues:
At institutions like the University of Colorado Boulder, science and engineering librarians operate within structured liaison frameworks, with some positions serving as one of just three subject specialists for entire colleges. The University of Alabama Libraries positions these roles as tenure-track faculty appointments, reporting to the Director of Branch Library and Research Data Services.1
While the titles are sometimes used interchangeably, subtle differences exist. Engineering librarians often focus more heavily on patents, technical standards from organizations like ASTM and ISO, and technical reports. Science librarians tend to emphasize journal literature, research datasets, and laboratory protocols. Both roles increasingly require fluency in bibliometric analysis and research impact assessment.
The role has expanded significantly in recent years. Responsibilities that barely existed a decade ago now form core parts of many positions: supporting computational research workflows, advising on data sharing and preservation, and helping researchers demonstrate the impact of their work through citation metrics.
Most positions require an ALA-accredited MLIS degree, though some institutions accept doctoral degrees in related science or health disciplines.1 Certain specialized roles, such as computational sciences or ecosystem sciences librarians, may accept graduate degrees in fields like computer science, mathematics, ecology, or environmental studies in lieu of traditional library credentials. Advertised salaries at research universities range from roughly $58,000 to $90,000, depending on experience and institutional context.
Science and engineering librarians fall under the broader federal classification of Librarians and Media Collections Specialists. According to the Occupational Employment and Wage Statistics program from the U.S. Bureau of Labor Statistics (2025 data), roughly 133,790 professionals work in this category nationwide. While the BLS does not break out a separate pay line for science librarians specifically, the figures below provide the most reliable national benchmark for the profession. Specialized science librarians, particularly those in research universities or corporate R&D settings, often earn above the median due to their STEM subject expertise.
| Occupation | Total Employment | Mean Annual Salary | 25th Percentile | Median (50th Percentile) | 75th Percentile |
|---|---|---|---|---|---|
| Librarians and Media Collections Specialists | 133,790 | $72,840 | $56,310 | $68,270 | $84,480 |
| Librarians, Curators, and Archivists (Broad Group) | 234,910 | $63,900 | $45,480 | $60,470 | $78,000 |
The salary range for librarians and media collections specialists spans roughly $28,000 from the lower to upper quartiles. Science librarians who hold STEM credentials or subject-matter expertise tend to cluster in the upper quartiles of this distribution, often commanding salaries well above the national median. With approximately 133,790 professionals employed nationally, the field offers a sizable job market alongside meaningful earning potential for those with specialized backgrounds.
Salaries for librarians and media collections specialists vary significantly across states, shaped by cost of living, institutional funding, and demand. The table below presents 2025 data from the Bureau of Labor Statistics for the 25 highest-paying states. Science librarians in research-intensive states such as California, Maryland, and New York tend to earn well above the national median, while states with lower living costs generally offer more modest compensation.

Where a science and engineering librarian works now shapes pay at least as much as what they do, and the gap between academic and corporate settings has become a defining feature of the field. PayScale's 2026 data for academic librarians shows a national base range of roughly $51,000 to $86,000, with entry-level total compensation near $49,320.
ARL member libraries track more than 14,000 professional positions, but 2026 ARL salary survey data does not break out a separate science or STEM librarian figure. For R1 university roles, the best available academic librarian salary benchmark remains the broad PayScale range: entry-level total compensation is about $49,320, while total compensation across experience levels runs from about $50,000 to $87,000. Research librarian postings show a much wider spread, with reported annual pay from roughly $117,587 at the 25th percentile to $197,870 at the 75th percentile, but that wider occupational figure includes settings beyond academic libraries.
Corporate science librarian roles, particularly in pharmaceutical and biotechnology research environments, commonly outpace academic pay by an estimated 15 to 30 percent. Those premiums come with tradeoffs: less institutional job security, more project-based fluctuation, and fewer tenure-style protections. A recent Biomedical Research Librarian posting in Bethesda listed a monthly range of about $6,667 to $9,167, which illustrates a corporate contract role more than a tenure-track library appointment. However, no 2026 corporate science librarian salary survey figure was available.
For health sciences librarian roles, which often sit near government and medical research settings, Glassdoor's 2026 estimate puts total pay at about $97,501, with an average base of $90,568 and about $7,033 in additional pay. This estimate is based on a small sample of reported salaries. Sources do not yet provide a separate 2026 figure for NIH, DOE national labs, or other federal science librarian positions, so federal laboratory pay remains a gap in current data.
Special librarian salary by sector is the least standardized of the four settings. PayScale's 2026 national librarian range runs from about $44,000 to $81,000, while academic librarians sit slightly higher. Science-focused special libraries may fall between academic and corporate levels depending on the institution, parent organization, and local market, but without a dedicated 2026 special library salary survey, students should treat the generic library science salary range as a floor rather than a specialty benchmark.
Years on the job move a science librarian's paycheck more reliably than almost any other single factor, and the climb is steep enough that early-career patience pays off literally.
Research libraries don't publish salary tables broken out specifically for science and engineering specialists, but the Association of Research Libraries' broader professional categories offer a useful proxy for how pay scales with tenure. Entry-tier professional staff average roughly 13 years of combined experience and about $82,300 annually, while those who move into management (around 15 years of experience) average closer to $91,400. Senior managers, with about 18 years behind them, average $112,600, and library directors, typically 22-year veterans of the field, average $177,800. Older ARL data on university librarians specifically showed entry-level pay landing at 60 to 70 percent of senior-level pay, a spread that has likely persisted even as dollar figures have risen. Science and technology subject specialists in ARL libraries average about 15.7 years of experience, putting a typical science librarian somewhere in the middle to upper end of this ladder rather than at the entry rung.
Hiring managers and job postings in academic and corporate settings frequently treat a second STEM degree, whether a bachelor's or master's in chemistry, biology, engineering, or a related field, as a meaningful differentiator, and anecdotal hiring data suggests it can translate into a few thousand dollars of additional starting salary versus an MLIS alone. No major published salary survey isolates this premium with precision, so treat any specific dollar figure as directional rather than guaranteed. What's clearer is that candidates with a subject-matter background tend to be more competitive for specialized postings in the first place, which indirectly affects pay by opening doors to higher-paying library science careers.
Data science certificates, bioinformatics training, and GIS coursework increasingly separate applicants in competitive searches, particularly for research-data-support and data-librarian hybrid roles that blend science liaison work with technical consulting. These credentials won't guarantee a raise, but they widen the pool of jobs a candidate can pursue.
Faculty status, common for science librarians at many research universities, matters just as much. Tenure-track or tenure-equivalent appointments often come with distinct salary scales, sabbatical eligibility, and promotion-linked raises unavailable to staff-status peers. Professional certifications, such as the AHIP credential from the Medical Library Association's Academy of Health Information Professionals or emerging data management credentials, can also sharpen a candidate's profile in tight, specialized markets.
Although both roles sit under the broader STEM librarian umbrella, science librarians and engineering librarians differ in the collections they manage, the information formats they teach, and the industries that hire them. The comparison below breaks down those differences across five practical dimensions so you can gauge which path aligns with your interests and earning goals.
| Dimension | Science Librarian | Engineering Librarian |
|---|---|---|
| Typical Subject Focus | Biology, neuroscience, chemistry, psychology, and other natural and life sciences within colleges of arts and sciences | Mechanical, civil, electrical, and related engineering disciplines, often embedded in a College of Engineering and its affiliated research labs |
| Key Resources Managed | Peer-reviewed journal databases, research datasets, lab protocols, open-access repositories, and biomedical reference tools | Patents, technical standards, conference proceedings, technical reports, and other forms of gray literature alongside traditional databases |
| Common Employers | University libraries supporting science departments, medical and research institutions, and government science agencies | Academic engineering libraries, corporate R&D information centers, and organizations tied to engineering education (such as ASEE member institutions) |
| Required Credentials and Skills | ALA-accredited MLIS plus demonstrated ability in data literacy, open educational resources, scholarly communication advising, and course-integrated instruction in the sciences | ALA-accredited MLIS with strong training in engineering literature, patent and standards information literacy, data management, and the ability to interpret technical documents for students and practitioners |
| Reported Salary Range | Approximately $65,200 per year based on recent aggregate data | Approximately $65,500 to $83,600 per year based on recent aggregate data, reflecting a potential premium at the upper end |
The Bureau of Labor Statistics projects 3% job growth for librarians and library media specialists over the 2025 to 2035 decade, a rate described as about as fast as the average for all occupations.1 Roughly 12,600 openings are expected each year, driven largely by the need to replace professionals who retire or change careers.1 While BLS does not break out projections specifically for science or STEM librarians, several demand signals point to steady or growing need in this niche, mirroring broader Library Hiring Trends.
Three trends are shaping demand for science and engineering librarians in 2026:
Association of Research Libraries workforce studies note that professional positions at ARL member libraries grew at roughly 1% per year over recent decades, and the emphasis on data-intensive services has only accelerated since then.
Career progression for STEM librarians generally follows a clear ladder:
A wave of retirements among baby-boomer librarians is expected to continue opening senior positions through the late 2020s, creating upward mobility for mid-career professionals.
STEM librarians who develop skills in data science, informatics, or metadata standards can move into adjacent roles that often carry higher salaries:
These pivots leverage the same combination of subject expertise and information organization that defines science librarianship, making the library science career path broader than it might first appear.
Below are answers to some of the most common questions prospective students ask about science librarian salaries, qualifications, and career options. Figures cited here reflect the most recent Bureau of Labor Statistics data for librarians and library media specialists.
