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.

While it used to be thought that the lychee needed an acid soil,
experience has shown that this is not the case. It has grown well
on volcanic sandy loams with a pH value of about 6.5 in Central America.
and it tolerates the calcareous soils of southern Florida and Cuba. On
stiff, impermeable sandy clays in Honduras it has not done well, but
neither have most other fruit trees. Nangos are an exception, avocados
are not. On the whole, it seems safe to say that the lychee grows
well in many tropical and subtropical climates, so long as it is not
pushed too far up against the frost line; that it is not exacting as
regards soils, if they are well drained; but that it is highly temper-
amental, if one can use such a term in horticulture - and that much
attention will have to be given to the search for the best varieties
best adapted to any given region, assisting the tree in
having the proper dormancy to let it build up reserves for fruit pro-
duction, where this is not provided by an adequate amount of cold
weather, which means that we must count on a period of dry weather,
and proper control of nutrition. It seems something like the case of
the mango: in this regard: Too much nitrogen in the soil
at the wrong time, too high a nitrogen intake (in some instances to
be controlled through the fertilizer program) and most probably, a
few other factors not yet fully understood.

Propagation

When a fruit tree of great commercial importance has been propa-
gated for some two thousand years, in a country of highly skillful
horticulturists, by a simple and inexpensive vegetative means, it
often takes some time to develop improved techniques. This seems to
be the case with the lychee. When a fruit has been developed through
selection of superior seedlings or valuable mutations, Vegetative
propagation is of course essential. The Chinese have used the method
