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.

Dear Dave,

Thanks for your letter of November 2, which reached
me today, having been forwarded from the SI on an irregular
basis.

Right now, as my address will indicate, nothing is
happening. Since September 9 I have been down here collecting
ferns. I'll be back in Washington by mid-December, and
will continue recoding my present data. Wagner and I are
getting together to talk over continuing the work on December
18; we may approach the NSF for funds. My present method
is in need of improvement, as we discussed at NY awhile ago.
But whether anything more comes of it or not, I'll recode
my data for your method, as I know the results will be of
interest to you as well as to us.

I have nothing down here to send you, unless I can get
the use of an office copier in the HQ of Archbold's plantations.
He has put up part of the money for the Smithsonian Biol.
Surv. of Dominica, and we are quartered at one of his plant-
ations. If nothing works out with the copier here, I'll send
you a xerox of the relevant parts of my dissertation by mid-
December. Wish I could do more, but am helpless in this back-
water. The only thing published is an explanation of Wagner's
method in Benson's grey-covered Plant Taxonomy book. Back-
ground is in Danser's 1950 article in Bibl. Biothecet. D,
4(3).

Eventually University Microfilms at Ann Arbor (no
connection with the University of Michigan) will publish,
as they say, my dissertation on microfilm. Xerox copies
will be available. I'll let you know when I find out if
it is ready in that medium. Actually, it may be out now--
I don't know.

How do you like Fort Collins. Bit of a change from NY,
isn't it. Perhaps you have met Roger Peterson of the Foxt
