Reference excerpt

Minnie Earl Sears (November 17, 1873 – November 28, 1933) formulated the Sears List of Subject Headings, a simplification of the Library of Congress Subject Headings. In 1999, American Libraries named her one of the "100 Most Important Leaders We Had in the 20th Century".

Life and work Sears was a native of Lafayette, Indiana, and was awarded a B.Sc. from Purdue University at age 18, the youngest graduate in her class. She received an M.Sc in 1893. In 1900 the University of Illinois awarded to her a Bachelor of Library Science degree. Sears had a long career as a cataloguer and bibliographer at a variety of libraries (Bryn Mawr College, University of Minnesota, New York Public Library), before she joined the publishing company H. W. Wilson Company in 1923 to publish her List of Subject Headings for Small Libraries. The book provides a list of subject headings for small libraries to use in lieu of Library of Congress Subject Headings. Library of Congress headings are often not as useful for small libraries because they are too detailed. Sears's List of Subject Headings also offers small libraries guidance on how to create their own new subject headings consistently when necessary. In order to create her subject headings, Sears consulted small and medium-sized libraries throughout the country to discern patterns of usage. She then developed her own system, based in part on the Library of Congress Subject Headings, but with a simplified subject vocabulary. In Sears's system, common terms are much preferred over scientific and technical terms. Her system also allowed individual libraries the authority to create their own subject headings. The Sears model is not meant to serve as a standardized bridge for union catalogs, but rather as a model "for the creation of headings as needed". Like the Library of Congress Subject Headings, Sears's system is a subject list arranged in alphabetical order, making use of overarching subject categories and hierarchical subject subdivisions. However, Sears's headings favor natural language. Her headings make use of only four types of headings: topical, form, geographic, and proper names. She also tended to convert inverted headings into direct entries. In the third edition of the book (1933), Sears added a section called, "Practical Suggestions for the Beginner in Subject Heading Work". These "Principles of the Sears List" were eventually published as a separate document and became a widely used teaching tool for library schools. In subsequent editions, Sears's subject headings have also been linked to appropriate Dewey Decimal Classification numbers. In addition to creating the List, Sears edited the Standard Catalog for Public Libraries of the American Library Association, and an edition of the Standard Catalog for High School Libraries. She eventually left H.W. Wilson to teach at the Columbia University School of Library Service, where she started the first graduate degree course in cataloging. Sears also remained an active participant in the American Library Association and the New York Library Association. American Libraries names one contribution she is best known for as Essay and General Literature Index, of which she was co-editor from 1931 to 1933. After her death in 1933 at the age of 60, the book was eventually renamed in her honor to the Sears List of Subject Headings. In 2018, Grey House Publishing purchased the Sears List from EBSCO. The 23rd edition of the Sears List of Subject Headings was published in print and through an online database in 2022.

Worked examples

Example 1 — a first encounter with Minnie Earl Sears

Start with the simplest possible case. Write down what Minnie Earl Sears claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Minnie Earl Sears before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Minnie Earl Sears ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Minnie Earl Sears

In research: Minnie Earl Sears appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Minnie Earl Sears in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Minnie Earl Sears is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1873 births, 1933 deaths, 20th-century American librarians, so understanding it makes those chapters shorter.
In everyday life: Look for Minnie Earl Sears outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
