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:

plant collecting and fieldwork in South America medicinal, culinary, or other traditional uses of plants chromosomes and plant classification early herbals and botanical illustrations botanical institutions exchanging plants, seeds, and specimens microscopy and photomicrography in botanical research How did botanists and gardeners introduce plants from one region to another? grafting, budding, and propagation of tropical fruit crops

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.

Dr. Cornelius A. VanDoren, Director
Estacion Experimental Agricola
En Tingo Maria
Tingo Maria, Peru

Dear Dr. VanDoren:

Thank you very kindly for your letter of last October including the results of your analyses of seventeen varieties of Yuca. Since I wrote to you, I have made a few changes in my approach on this particular plant as far as its taxonomy and genetics is concerned, in that I have asked the Department of Agriculture in Jamaica and the same American Agricultural Institute at Turrialba to cooperate in the cultivation of varieties collected from sources all over the world. We are hoping to bring together as much information concerning these varieties as possible in addition to learning something of the classification of them. I am hoping to establish these experimental plots sometime during the coming six months, and to be able to ask you to send viable specimens of whatever varieties you have in cultivation there in Tingo Maria and at other places you may be able to collect specimens from in Peru.

I have requested the assistance of Dr. Nevin Scrimshaw, in Guatemala, to assist in the nutritional studies of a similar basis to that which you have made at your station, plus the studies of the food values of the foliage as a concentrate in animal feed. In other words, we will try to find out as much as is possible to make Yuca a more useful agricultural plant. I shall let you know as soon as we are ready to receive specimens at these two stations and ask you at that time for specimens. I trust that this will not be too much of a difficulty to provide them. At the same time that I write you, I shall probably ask for pressed, dried specimens of each of the varieties in order that we can have some check as to the morphology of the varieties as it grew in this environment. I shall give you more explicit data at the next time. Thank you very kindly for your cooperation.

Very truly yours,

David J. Rogers
Assistant Professor of Biology
