Hunt Institute Archives Text Discovery Platform

Search a large and growing portion of our online collections, including handwritten documents.
PROTOTYPE

This prototype uses state-of-the-art artificial intelligence, including a vision-language model (VLM) capable of reading handwritten documents as well as typed and printed text, to create searchable transcriptions of digitized materials in the Hunt Institute Archives. This makes it possible to search the textual contents of individual pages, including material that may not be described in the archival catalog.

Use Keyword search for specific words, names, dates, scientific names, or phrases. Try Semantic search (experimental) to describe a topic, question, or kind of material when you do not know the exact wording used in the documents.

About the AI-generated transcriptions

The transcriptions are generated automatically from page images and may contain errors, especially with difficult handwriting, unusual names, multiple languages, image-quality problems, or complex layouts. They are intended primarily as a discovery aid rather than authoritative transcriptions.

Each result provides the generated transcription and links to the original digitized material and associated archival description so that readings can be checked against the source. The transcription workflow uses AI models run locally by the Hunt Institute.

About Keyword and Semantic search

Keyword search is the default and matches the wording in the transcriptions. Results contain all your terms. Use quotes for an exact phrase. Substring matching is supported, so aceae can find plant-family names ending in -aceae.

Semantic search (experimental) is useful when you know what kind of material you are looking for but do not know the words used in the documents. It ranks transcribed passages by similarity of meaning, so relevant results may not contain the exact words in your query.

Semantic queries can be broad research topics, descriptions of activities or relationships, or natural-language questions. For example:

Semantic search is not a chatbot: a question is used as a search query, and the system returns archival passages that appear conceptually related to it rather than generating an answer or summary. Short descriptions and ordinary research questions generally work better than lists of disconnected keywords. Quotation marks have no special meaning in Semantic mode. Cross-language matching may work in some cases, but it should not be treated as translation.

Keyword and Semantic search are complementary. Keyword search lets you require particular wording; Semantic search can surface differently worded passages about the same subject. Depending on the research question, trying both can reveal different useful material.

Open a result: use the prominent page-and-transcription link to see the metadata, PDF, and full transcription. Keyword-search terms are highlighted in the transcription.

Archives Collections Database (ArchivesSpace): the Collection, Item/Folder, and Digital Object links open the corresponding archival records. Collection-level dates describe the collection as a whole, not necessarily the specific item or page.

If a PDF does not load: on the detail page, use the Digital Object link, click “Go to file” in ArchivesSpace, and navigate to the page number shown here.

Current limitations
  • Automated transcriptions can contain missing or incorrect text or unintended repetition. Difficult handwriting, image quality, unusual layouts, and multiple languages can reduce accuracy. Always consult the original page image when an exact reading matters.
  • Semantic search remains experimental. Its rankings are an additional discovery aid, not a complete or definitive set of relevant results, and highly ranked pages can sometimes be only broadly related.
  • This is an active prototype. Search coverage, transcriptions, functionality, and the interface may continue to change as additional archival material is processed and the system is improved.

spur of propagating material - I wonder if we have Clementine mandarin
I am afraid not; we have one tree here in Antigua and the fruit is fine.
As for the avocados, I hope you can propagate and continue the
most promising varieties. That collection down below the new houses
is the fifth we have had in 20 years. Doctor Malan of South Africa
told us they had learned to lengthen the life of plantings where Phy-
tophthora is a problem by cutting down irrigation; and in my last two
years at Zamorano I tried that and it seemed to help. I thought the
trees would die from drought- we gave them no water during the dry
season, but they didn't. Of course they didn't grow much. Zamorano has
always been a source of propagating material of the best avocados and
I hope it can continue to be.
I am delighted that you are going to put Ceiba back on its feet.
And what you say makes me feel sure you plan to join us at the Miami
meeting of the Caribbean Region ASHS next March. The following year,
1962, it is planned to meet here in Guatemala and devote special
attention to deciduous fruits.
And now a last word on mangos: our colleagues in Florida are giving
up the commercial planting of Haden because they say it stops bearing
when it is 12 to 15 years of age. In Venezuela I saw, last year, at
least 20 trees which I know to be 30 years old and they were bearing
fine crops. I ask them in Florida, How do you know that your new
varieties such as Keitt and Kent and Zill won't stop bearing, here,
when the grafted trees are 12 to 15 yrs old, just like Haden. I am
still encouraging the planting of Haden in tropical America.
If you should come over this way at any time, do not fail to
spend a day or two with us here in Antigua. We have lots of room and
there is plenty to see in this region.
Sincerely,
