What Semantic Librarian includes

  • Semantic search, not keyword matching

    Search by meaning, not exact words. 'Photos of Melbourne in the 1950s' finds records described as 'aerial photograph, City of Melbourne, 1952' — even though the words don't overlap. Historical language, inconsistent cataloguing, and spelling variations are no longer barriers.

  • One search, eleven archives

    A single query searches Trove, PROV, Museums Victoria, NMA, VHD, ALA, ACMI, Geoscience Australia, GHAP, PM Transcripts, and IIIF collections simultaneously — from Trove's 1,500+ partners to ALA's 9,757 datasets. No more opening 11 tabs or learning 11 different search interfaces.

  • Attribution built into the data model

    Every result carries its source, licence, and attribution text. CC-BY compliance is structural — the _attribution array in search responses ensures downstream consumers can display proper credit automatically.

  • A card catalogue, not a library

    Semantic Librarian indexes metadata only — titles, dates, descriptions, coordinates, subjects, thumbnails. It never stores full content. Every result links back to the original source for the actual document, image, or record.

Transparency

Metadata Only

Indexes titles, dates, and descriptions. Never stores full content from archives.

Attribution-First

Every result carries its source, licence, and attribution text. CC-BY compliance is structural.

Non-Commercial

Free research tool. No paid tiers, no premium features, no revenue model.

Good Neighbour

Polite rate limiting, descriptive headers, and respect for institutional policies.

"I kept falling down rabbit holes on Trove — reading old newspaper articles from the 1920s, browsing PROV government archives from 150 years ago, exploring heritage buildings on VHD. But finding things was painful. Each archive had its own search, its own quirks, its own pagination. I'd spend an hour searching one site, then start again on the next. The collections are extraordinary. The search experience is not."

Who It's For

🎓

Academic Researcher

"How do I find primary sources across multiple archives for my thesis?"

Researchers who need to search comprehensively across Australian archives for a specific topic, period, or region.

You need: Cross-archive discovery that finds records keyword search misses.

🔍

History Enthusiast

"What happened in my local area 100 years ago?"

History buffs who explore out of curiosity — browsing old newspaper articles, looking up heritage places, discovering photographs of their town.

You need: A single search that finds the interesting stuff hidden across multiple platforms.

🌳

Genealogist

"How do I find records of my ancestors across different archives?"

Family history researchers tracing lineage through immigration records, court documents, newspaper mentions, and government archives.

You need: Cross-referencing records across archives that would take hours to search individually.

📚

Educator or Student

"Where can I find primary sources for my Australian history assignment?"

Teachers and students looking for original documents, photographs, and artefacts to support learning and assignments.

You need: Easy access to verified, attributable primary sources without navigating 11 separate platforms.

Questions about Semantic Librarian

What is Semantic Librarian?
Semantic Librarian is a free, non-commercial research tool that gives AI a unified metadata library across 11 Australian historical archive platforms. It uses semantic search to help you find historical images, newspaper articles, documents, maps, and records — without manually searching each site one by one.
Why is it called Semantic Librarian?
The name describes exactly what it does — a librarian that understands meaning, not just keywords. 'Semantic' because it uses AI to search by meaning rather than exact word matching. 'Librarian' because it knows every collection, every catalogue, and can point you to things you didn't know existed. It doesn't create or store the works — it helps you discover what's out there, then sends you to the original source.
Which archives does it search?
Semantic Librarian connects to 11 archive APIs, but each API is a gateway to many more institutions. Trove alone aggregates content from 1,500+ contributing organisations including every state library, the National Archives, the Australian War Memorial, and dozens of universities. The Atlas of Living Australia draws from 9,757 datasets across hundreds of museums, herbaria, and citizen science platforms. In total, Semantic Librarian gives you unified search across hundreds of institutions and hundreds of millions of records.
Is Semantic Librarian available to use?
Not yet as a public tool. Semantic Librarian is in the workshop — I'm using it personally and validating that the search results are genuinely useful across all 11 sources. There's no public release planned until the tool consistently helps people find things they couldn't find before.
Does Semantic Librarian store the actual content from archives?
No. Semantic Librarian indexes metadata only — titles, dates, descriptions, coordinates, subjects, and thumbnails. It never stores full article text, high-resolution images, or complete documents. Every result links back to the original source for the actual content.
What types of records can Semantic Librarian search?
Newspaper articles from 1803 to the present, historical photographs and maps, museum objects and artefacts, government archives and correspondence, heritage places and shipwrecks, historical aerial photography from 1928 to 1996, species and biodiversity records, historical placenames with coordinates, Prime Ministerial speeches and transcripts, films, TV programmes, videogames, court and immigration records, and Aboriginal and Torres Strait Islander cultural materials.
How many records are searchable?
The 11 APIs provide access to hundreds of millions of records. Trove alone aggregates approximately 308 million records including 254.6 million newspaper and gazette articles. The Atlas of Living Australia holds 101.5 million species occurrence records. Geoscience Australia has 1.2 million historical aerial photographs. Museums Victoria holds 17.2 million items. The actual number searchable through Semantic Librarian's semantic index is smaller — currently around 2 million indexed records with metadata — but every result links back to the full record at the original source.
Why share this if it's not available?
The problem of siloed Australian archives is real and widely felt. Sharing the approach — semantic search across unified metadata, with proper attribution — might be useful to others thinking about similar challenges. And the principles behind it (metadata-only, attribution-first, non-commercial) are worth discussing openly.
