Search Tips
For the Find Term or Note field, you may use AND and OR (all in upper case) [e.g., 1) windsor chairs, 2) chairs OR rockers, 3) chairs OR rockers OR armchairs, 4) bow-back AND windsor, 5) windsor AND (rockers OR chairs), 6) (windsor OR boston) AND (rockers OR chairs)]. Wildcard is the asterisk (*); right truncation only. To find an exact match rather than a key word in the Find Term field, use quotes [e.g., "chairs"]. If you wish to search the term and note together, click on the buttons for AND or OR.

The Medical Subject Headings (MeSH) thesaurus is a controlled and hierarchically-organized vocabulary produced by the National Library of Medicine. It is used for indexing, cataloging, and searching of biomedical and health-related information. MeSH includes the subject headings appearing in MEDLINE/PubMed, the NLM Catalog, and other NLM databases.
The PaST thesaurus is based on work supported by the National Science Foundation under Grant Number 1545762 and is maintained by the World Data Service (WDS) for Paleoclimatology. Data contributors are required to use terms from the PaST Thesaurus, or propose new terms in their submissions.
Although the thesaurus content remains essentially the same, there are some minor changes in field structure and labeling. For example, Public Note is now called Scope Note. Additionally, new fields were added to clarify term usage. For further information on these changes see "Fields in Term Record Displays" (via PPOC - About the Thesaurus).
Each database vendor includes an online thesaurus, although index term field labels vary across platforms. Check the search help for the system you are using to see how to search using index terms. If we have a search guide for your system, you'll also find the information there.
A thesaurus (pl.: thesauri or thesauruses), sometimes called a synonym dictionary or dictionary of synonyms, is a reference work which arranges words by their meanings (or in simpler terms, a book where you can find different words with same meanings to other words),[1][2] sometimes as a hierarchy of broader and narrower terms, sometimes simply as lists of synonyms and antonyms. They are often used by writers to help find the best word to express an idea:
The word "thesaurus" comes from Latin thēsaurus, which in turn comes from Greek θησαυρός (thēsauros) 'treasure, treasury, storehouse'.[7] The word thēsauros is of uncertain etymology.[7][8][9]
Until the 19th century, a thesaurus was any dictionary or encyclopedia,[9] as in the Thesaurus Linguae Latinae (Dictionary of the Latin Language, 1532), and the Thesaurus Linguae Graecae (Dictionary of the Greek Language, 1572). It was Roget who introduced the meaning "collection of words arranged according to sense", in 1852.[7]
Roget's Thesaurus, first compiled in 1805 by Peter Mark Roget, and published in 1852, follows John Wilkins' semantic arrangement of 1668. Unlike earlier synonym dictionaries, it does not include definitions or aim to help the user choose among synonyms. It has been continuously in print since 1852 and remains widely used across the English-speaking world.[20] Roget described his thesaurus in the foreword to the first edition:[21]
Roget's original thesaurus was organized into 1000 conceptual Heads (e.g., 806 Debt) organized into a four-level taxonomy. For example, debt is classed under V..mw-parser-output span.smallcapsfont-variant:small-caps.mw-parser-output span.smallcaps-smallerfont-size:85%ii.iv:[22]
The book starts with a Tabular Synopsis of Categories laying out the hierarchy,[23] then the main body of the thesaurus listed by the Head, and then an alphabetical index listing the different Heads under which a word may be found: Liable, subject to, 177; debt, 806; duty, 926.[24]
The Unified Astronomy Thesaurus (UAT) is an open, interoperable and community-supported thesaurus which unifies the existing divergent and isolated Astronomy & Astrophysics thesauri into a single high-quality, freely-available open thesaurus formalizing astronomical concepts and their inter-relationships. The UAT builds upon the existing IAU Thesaurus with major contributions from the Astronomy portions of the thesauri developed by the Institute of Physics Publishing and the American Institute of Physics. We expect that the Unified Astronomy Thesaurus will be further enhanced and updated through a collaborative effort involving broad community participation.
The main impetus behind the creation of a single thesaurus has been the wish to support semantic enrichment of the literature, but we expect that use of the UAT (along with other vocabularies and ontologies currently being developed in our community) will be much broader and will have a positive impact on the discovery of a wide range of astronomy resources, including data products and services.
The thesaurus is limited in depth and specificity of coverage. It does notattempt to replicate existing controlled vocabularies such as AGI's GeoRef.The intention is to provide sufficient contextual cues for the informationseeker to determine the relevance of a resource for his or her concern, notto locate precisely the answer to a specific user question.
As in any profession, osteopathic medicine has developed a unique terminology integral to its professional identity. It is the means by which specialized knowledge is transmitted within the profession, to the public, and to future generations. To maintain control, currency, clarity, and consistency, many professions now maintain their terminology in a structured thesaurus format.
Funding for the thesaurus editor position was contributed by the American Osteopathic Association. Members of the American Academy of Osteopathy and its Louisa Burns Osteopathic Research Committee contributed a great deal of time and expertise to help make this project a reality.
Recently, various groups within the osteopathic profession discovered that the current sources of osteopathic terminology were inadequate to meet their needs. They determined that, especially in the digital age, an authoritative osteopathic thesaurus was essential to the increasing number of professional activities requiring accurate, consistent descriptive terminology. These activities included:
The Authorized Osteopathic Thesaurus (AOT) is the official thesaurus for osteopathic medicine, defining the meaning and interrelationships of those terms that have a unique meaning in osteopathic medicine.
Personal Names Authority List provides controlled name forms and spellings. Unlike the Subject and the Geographic lists, it is non-hierarchical (there are no broader/narrower, or related term designations). This list is designed to provide name form consistency and, through the use of a "description" (DSC) note field, enable users to distinguish between same or similar names and to determine whether the person/name is appropriate to their indexing or searching needs. Organization Names Authority List is an alphabetical authority list of name forms for organizations listed in ICPSR metadata as funding agencies or as corporate authors/principal investigators. Subject Thesaurus is an alphabetical listing of social science subject terms. The scope of this thesaurus is multidisciplinary and is intended to reflect the subject range of the ICPSR archive. Social science disciplines represented include: political science, sociology, history, economics, education, criminal justice, gerontology, demography, public health, law, and international relations Geographic Names Thesaurus provides guidance on the preferred and/or current names of geographic and geopolitical entities. It is hierarchically arranged using broader/narrower notation, allowing one to navigate the relationships among region, continent, country, and in some cases, cities. Scope notes briefly detailing the history of country name changes are included along with instructions and restrictions for their use and application.A Bibliography (PDF 12K) of reference documents and thesauri used to prepare the ICPSR controlled vocabulary system
