    markdown: >-
      A librarian exists to connect people with the information, ideas, and
      stories they need —

      and to build and steward the systems that make that connection possible at
      scale, for

      everyone, regardless of who they are or what they can pay. The work looks
      simple (helping

      someone find a book) and is two crafts at once: the public craft of
      understanding what a

      person really needs, and the invisible craft of organizing the record of
      human knowledge so

      it can be found at all. A librarian is the human index between a question
      and an answer, and

      the guardian of the freedom to ask the question.
  - heading: Core Mission
    markdown: >-
      Help any person find, evaluate, and use the information they need —
      efficiently, without

      judgment, and in privacy — while maintaining the organized, openly
      accessible collections and

      systems that make finding possible for the next person too.
  - heading: Primary Responsibilities
    markdown: >-
      The visible work is the desk; the actual work spans service, organization,
      and stewardship. A

      librarian conducts reference interviews to surface the real need behind a
      vague question;

      teaches information literacy so people can find and judge sources
      themselves; develops the

      collection — selecting, acquiring, and weeding to keep it relevant and
      balanced; catalogs and

      applies metadata so items are findable; defends intellectual freedom
      against censorship and

      challenges; protects the privacy of what patrons read and search;
      evaluates and recommends

      sources across a flood of digital and AI-generated content; manages access
      to databases,

      e-resources, and physical space; and serves as a neutral guide who points
      to all sides rather

      than prescribing one. Underneath it is a constant ethical posture: serve
      the patron's

      inquiry, not your opinion of it.
  - heading: Guiding Principles
    markdown: >-
      - **The question behind the question.** What a patron asks for is rarely
      what they need; the
        reference interview exists because "do you have books on Rome" hides a kid with a report on
        Roman aqueducts due tomorrow.
      - **Access is the whole point.** Organization, cataloging, and collections
      all serve one end —
        that someone can find the thing. An unfindable item might as well not exist.
      - **Intellectual freedom is non-negotiable.** The library holds materials
      people disagree with
        on purpose; the answer to a book someone hates is another book, not a removed one.
      - **The patron's privacy is sacred.** What someone reads, borrows, or
      searches is nobody's
        business, including the state's, absent due process.
      - **Neutrality is a discipline, not apathy.** Point to the range of
      credible views; your job is
        to inform inquiry, not win the patron to your side.
      - **Meet every patron without judgment.** The same quality of help goes to
      the scholar, the
        conspiracy theorist, the homeless patron, and the child.
      - **Teach the person to fish.** A good answer solves today's question;
      teaching the search
        strategy solves the next hundred.
  - heading: Mental Models
    markdown: >-
      - **The reference interview.** A structured conversation — open questions,
      paraphrase,
        follow-up — to move from the patron's stated request to their actual need. The most important
        skill, because the first question is almost always imprecise.
      - **Precision vs. recall.** Every search trades returning only relevant
      results against
        returning all relevant ones. Broaden terms for recall, add facets for precision; the balance
        depends on the need.
      - **Controlled vocabulary vs. natural language.** Subject headings (LCSH,
      MeSH) impose
        consistent terms so synonyms collapse and findability rises; keyword search is flexible but
        noisy. Know when to switch registers.
      - **Information literacy (ACRL Framework).** Authority is constructed and
      contextual;
        information has value; research is inquiry; scholarship is conversation; searching is
        strategic. The model patrons most need taught.
      - **Classification as a map.** Dewey and Library of Congress aren't just
      shelf order; they're a
        theory of how knowledge relates, with each system's biases baked in.
      - **The collection as a living organism.** It must be fed (acquisition)
      and pruned (weeding); a
        collection that only grows becomes a warehouse where nothing is found.
      - **Lateral reading.** Don't evaluate a source from within it; check what
      others say about it,
        the way fact-checkers and SIFT assess credibility.
  - heading: First Principles
    markdown: >-
      - A document that can't be found is functionally lost, no matter how good
      it is.

      - People rarely state their real need on the first try; the request is a
      starting point.

      - The freedom to read requires that no one watch what you read.

      - Every classification scheme encodes the worldview and biases of its
      makers.
  - heading: Questions Experts Constantly Ask
    markdown: >-
      - What does this patron actually need, behind what they asked?

      - What's the deadline, the format, the depth — a fact, an overview, or
      exhaustive research?

      - Am I broadening for recall or narrowing for precision here?

      - Who created this source, why, and what authority stands behind it?

      - Is this request a privacy matter I must protect?

      - Is a challenge to this material a reason to reconsider, or a reason to
      defend it?

      - Where will the patron's next, related question take them — can I teach
      the strategy?

      - Does the collection reflect the whole community, or only part of it?
  - heading: Decision Frameworks
    markdown: >-
      - **The reference interview sequence.** Open with broad questions,
      paraphrase to confirm,
        narrow with follow-ups about scope/format/deadline, then search — and circle back to verify
        the result actually meets the need.
      - **Selection and weeding (CREW / MUSTIE).** Acquire by community need,
      demand, balance, and
        authority; weed what's Misleading, Ugly, Superseded, Trivial, Irrelevant, or available
        Elsewhere. A weeded shelf serves better than a full one.
      - **Handling a challenge.** A patron objects to a book: listen, take the
      formal reconsideration
        request, keep the item available during review, and evaluate against the
        collection-development policy and intellectual-freedom principles — not the loudest complaint.
        Removing on demand is censorship.
      - **Privacy vs. a request for records.** Release patron records only with
      proper legal process
        (a valid subpoena, not a casual ask); consult policy and counsel; default to protection.
      - **Source evaluation (SIFT / CRAAP).** Stop, Investigate the source, Find
      better coverage,
        Trace claims to origin; or weigh Currency, Relevance, Authority, Accuracy, Purpose. Read
        laterally rather than trusting surface polish.
  - heading: Workflow
    markdown: >-
      1. **Receive the question.** A patron, a chat message, an email — almost
      always
         underspecified.
      2. **Conduct the reference interview.** Open questions, paraphrase,
      clarify scope, format,
         depth, and deadline until the real need is clear.
      3. **Strategize the search.** Choose sources (catalog, database, web),
      pick controlled
         vocabulary or keywords, and set the precision/recall balance to the need.
      4. **Search and evaluate.** Run it, assess the results' credibility
      laterally, refine terms
         iteratively.
      5. **Deliver and teach.** Hand over the result and, where the patron's
      open to it, show the
         strategy so they can do it next time.
      6. **Confirm and follow up.** Check it actually answered the question;
      offer the next step.

      7. **Steward the collection (ongoing).** Select to community need, catalog
      with accurate
         metadata, weed on schedule, defend against challenges, and curate access.
      8. **Protect throughout.** Keep patron interactions and records private as
      a constant duty.
  - heading: Common Tradeoffs
    markdown: >-
      - **Precision vs. recall.** Tight searches miss relevant material; broad
      ones bury it in noise.
        Tune to whether the patron needs the best answer or all the answers.
      - **Breadth vs. depth of collection.** A finite budget forces choices
      between covering
        everything thinly and going deep where the community needs it.
      - **Neutrality vs. curation.** Selecting a collection is unavoidably a set
      of choices; the
        librarian shapes access while striving to represent the full range, not their taste.
      - **Access vs. privacy.** Personalization and recommendations improve
      service but require
        tracking behavior the profession is sworn to protect; lean toward privacy.
      - **Open access vs. licensing reality.** Patrons want everything free and
      instant; vendor
        contracts, DRM, and budgets constrain what's deliverable.
      - **Serving the individual vs. serving the system.** Time perfecting one
      patron's search is
        time not spent cataloging for the thousand who'll never reach the desk.
  - heading: Rules of Thumb
    markdown: >-
      - Never answer the first question; clarify it first.

      - Ask "what will you do with this?" — purpose reshapes the whole search.

      - The answer to a book you hate is another book.

      - A full shelf where nothing is found is worse than a weeded one.

      - Read laterally; leave the suspicious site to check what others say about
      it.

      - Protect the record of what people read as if it were medical history.

      - Teach the search, not just deliver the result, when there's time.

      - "I don't know, but I know how to find out" is a complete and honest
      answer.
  - heading: Failure Modes
    markdown: >-
      - **Answering the wrong question.** Skipping the reference interview and
      confidently solving a
        problem the patron didn't have.
      - **The unweeded collection.** Letting shelves fill with outdated,
      inaccurate material until
        findability and credibility both collapse.
      - **Quiet censorship.** Not selecting, or burying, materials the librarian
      personally
        disapproves of — soft censorship that looks like neutral curation.
      - **Caving to a challenge.** Pulling a book because someone complained,
      without due process,
        ceding intellectual freedom to the loudest voice.
      - **Privacy leakage.** Disclosing what a patron read to a parent, partner,
      or officer without
        proper process.
      - **Imposing the librarian's view.** Steering a patron to "the right
      answer" instead of the
        range of credible sources.
      - **Catalog neglect.** Sloppy metadata that makes good items invisible to
      the people searching
        for them.
  - heading: Anti-patterns
    markdown: >-
      - **"What do you want?" then silence** — taking the request literally and
      skipping the
        interview.
      - **Tech-support gatekeeping** — making patrons feel stupid for not
      knowing the system.

      - **The shushing stereotype as policy** — prioritizing silence and order
      over access and
        welcome.
      - **Vendor lock-in by default** — accepting whatever a database vendor
      packages instead of
        evaluating fit and terms.
      - **Recommendation surveillance** — building reading-history features that
      erode the privacy
        the profession protects.
      - **Curation by taste** — a collection that mirrors the librarian's
      preferences, not the
        community's needs.
      - **"Just Google it"** — abdicating the evaluation and strategy that's the
      actual value.
  - heading: Vocabulary
    markdown: >-
      - **Reference interview** — the structured conversation that uncovers a
      patron's real
        information need.
      - **Precision and recall** — the relevance-vs-completeness tradeoff in any
      search.

      - **Controlled vocabulary** — a standardized set of subject terms (LCSH,
      MeSH) for consistent
        retrieval.
      - **MARC** — Machine-Readable Cataloging, the standard record format for
      bibliographic
        metadata.
      - **Dewey Decimal / Library of Congress Classification** — the two
      dominant systems for
        organizing and shelving by subject.
      - **Collection development** — the policy-guided selection, acquisition,
      and weeding of
        materials.
      - **Weeding (deselection)** — removing outdated or unused items to keep a
      collection useful.

      - **Intellectual freedom** — the right to access information and ideas
      without censorship.

      - **Information literacy** — the ability to find, evaluate, and use
      information effectively and
        ethically.
      - **OPAC / discovery layer** — the public catalog and search interface
      patrons use.
  - heading: Tools
    markdown: >-
      - **The catalog and ILS** — the integrated library system and OPAC; the
      spine of findability
        and circulation.
      - **Cataloging standards** — MARC, RDA, Dewey/LC, and authority files for
      consistent metadata.

      - **Subscription databases and discovery layers** — the licensed scholarly
      and reference
        content beyond the open web.
      - **Controlled vocabularies and thesauri** — LCSH, MeSH, and subject
      authorities.

      - **Collection-development and reconsideration policies** — the framework
      that governs
        selection and defends against challenges.
      - **Citation, evaluation, and discovery tools** — for teaching information
      literacy.

      - **The reference interview itself** — the irreplaceable human instrument.
  - heading: Collaboration
    markdown: >-
      A librarian works with patrons first, but the role is networked. They
      collaborate with fellow

      librarians across reference, cataloging, and acquisitions; with teachers
      and faculty to embed

      information literacy into coursework and support research; with publishers
      and database vendors

      in licensing negotiations; with technologists who maintain the ILS and
      discovery systems; with

      archivists on preservation; and with the community and its governing body,
      who fund the

      institution and to whom intellectual-freedom challenges ultimately
      escalate. The recurring

      friction lives between access and constraint — what patrons want versus
      what budgets, licenses,

      and policies allow — and between professional ethics and external pressure
      to restrict

      materials or surrender patron data.
  - heading: Ethics
    markdown: >-
      A librarian holds the public's trust as both a guide to information and a
      guardian of the

      freedom to seek it. The duties (ALA Code of Ethics, Library Bill of
      Rights): provide the

      highest service to all without discrimination; uphold intellectual freedom
      and resist

      censorship, including the soft censorship of selective non-selection;
      protect each patron's

      right to privacy and confidentiality in what they seek, receive, and read;
      distinguish private

      views from professional duties so personal belief doesn't ration access;
      treat colleagues

      fairly and credit their work; and ensure equitable access across the
      digital divide. The hard

      cases — a parent demanding a child's reading record, a government request
      for borrowing data, a

      community campaign against a book, an AI tool that quietly logs queries —
      rarely have painless

      answers, but the posture is clear: default to access, default to privacy,
      and make any

      restriction follow due process rather than the loudest demand.
  - heading: Scenarios
    markdown: >-
      **The vague reference request.** A patron says, "Do you have anything on
      the Civil War?" The

      novice walks them to the 973 shelf and leaves. The expert opens the
      interview: what about the

      Civil War — a battle, a person, the causes? Is this for school, personal
      interest, or

      genealogy? When's it due, and how much do you need? Two questions in, it
      emerges the patron is

      researching whether an ancestor served in a specific regiment — a
      genealogy and primary-source

      problem, not a browse-the-shelf problem. The right answer is a regimental
      roster database and a

      pension-records guide, not a general history. The reference interview just
      changed the entire

      search; the literal request would have failed.


      **A challenge to a book.** A parent demands the library remove a
      young-adult novel they find

      objectionable and threatens to escalate to the board. The reactive move is
      to quietly pull it

      and avoid conflict. The expert treats it as a defense of intellectual
      freedom: listens

      respectfully, explains that one family's objection doesn't decide access
      for the whole

      community, and offers the formal reconsideration process. The book stays
      on the shelf during

      review. The committee evaluates it against the collection-development
      policy and the Library

      Bill of Rights, not against the volume of the complaint. The patron can
      choose what their own

      child reads; they cannot choose for everyone else's.


      **A request for borrowing records.** An officer comes to the desk asking,
      without a warrant,

      what a particular patron has been reading, citing an investigation. The
      librarian feels the

      pull to cooperate, but patron records are confidential, and the answer is
      a firm, polite

      refusal pending proper legal process: a valid subpoena or court order,
      reviewed by counsel. The

      librarian doesn't confirm or deny the patron's activity, follows the
      privacy policy, and

      documents the request. Protecting the freedom to read without surveillance
      is not obstruction;

      it's the job.
  - heading: Related Occupations
    markdown: >-
      A librarian shares the information craft of several roles but is defined
      by neutral,

      privacy-protected service across an entire community's inquiries.
      Archivists do adjacent work

      focused on preserving and arranging unique, permanent records rather than
      circulating published

      collections. Technical writers organize and present information for
      findability, much like

      cataloging, but author it for a single product. UX researchers share the
      discipline of

      uncovering a user's real need behind their stated request — the reference
      interview is a cousin

      of the research interview. Teachers and the librarian both teach
      information literacy. Research

      scientists are expert patrons whose literature searches the librarian
      enables.
