Homosaurus

Homosaurus is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Homosaurus rather than just read about it. In short: Homosaurus is a thesaurus or controlled vocabulary dedicated to LGBTQ+ terms. It aims to replace and complement outdated and disparaging definitions in broader vocabularies such as the Library of Congress Subject Headings, and has been used by the Library of Congress since 2016.

Key takeaways

Homosaurus belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Homosaurus to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Homosaurus from memory before moving on to harder problems.

Reference excerpt

Homosaurus is a thesaurus or controlled vocabulary dedicated to LGBTQ+ terms. It aims to replace and complement outdated and disparaging definitions in broader vocabularies such as the Library of Congress Subject Headings, and has been used by the Library of Congress since 2016. The project was started in 1982, where it was made as a standalone vocabulary to describe the collection for the IHLIA LGBT Heritage in Dutch. It was significantly expanded in 1987, and was merged with a queer-focused vocabulary from Anna Blaman Huis. In 1997, it was translated into English as A Queer Thesaurus, which was available in both Dutch and English. In 2013, it was renamed to the Homosaurus and expanded with a focus on reducing its bias towards white cisgender gay men. In 2016, it was decided to reduce the scope of the vocabulary to LGBTQ+ terms only. Since then, it has been used to support any use for collating LGBTQ+ works. The thesaurus has been translated into Swedish and French. An effort to translate the project into Spanish was started in 2023 in collaboration with the San Francisco Public Library, UCLA Chicano Studies Research Center, and the Arizona Queer Archives when the U.S. National Endowment for the Humanities granted 350,000 dollars to do so. It is slated to finish in late 2026.

Worked examples

Example 1 — a first encounter with Homosaurus

Start with the simplest possible case. Write down what Homosaurus claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Homosaurus 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 Homosaurus 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 Homosaurus

In research: Homosaurus appears in science 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 Homosaurus 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: Homosaurus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Controlled vocabularies, LGBTQ and education, LGBTQ literature, so understanding it makes those chapters shorter.
In everyday life: Look for Homosaurus 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.

Frequently asked questions

What is Homosaurus in simple terms?

Why does Homosaurus matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Homosaurus?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
