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.

frequently have interesting colors or unusual patterns which, either in nature
on in gardens, give us pleasure. In the respect, perhaps the most outstanding
tree of the northeastern woodlands is the paper, or white birch. In late
fall, the white bark is striking contrast to an otherwise dull grey or brown
landscape. Combine these trees with a background of evergreen hemlock or
pine or spruce and very pleasing effects are produced. A shrub with unusual
bark patterns in Euonymus alata, the burning bush. Corky extensions of the
bark form wings on each side of all the branches, and when snow falls, the
lacy patterns of snow caught on the wings are very handsome. Other bark
patterns are interesting for deep fissures in the bark, giving contrasting
light patterns; striped barks of such trees as moosewood (Acer pennsylvanicum)
produce very desirable effects.

We mentioned earlier that the veins of leaves make interesting color
pattern variations. Leaves have other characteristics, particularly in form,
which make them valuable as ornamentals. Indeed, florists take advantage
of this in construction of bouquets and corsages. Seldom are these made with
flowers alone, and even the lovely orchid corsage has some sort of green
foliage background. The foliage selected for these backgrounds has to pro-
vide a beautiful setting for the center-stage flower and also must last at
least as long as the flowers. For this reason, leaves with a heavy cuticle,
or thickened and succulent interior, are selected. Leaves, like flowers,
vary in the length of time they will remain fresh and colorful after cutting.
Kinds of Plants Used as Ornamentals

From the foregoing discussion it should be evident that almost any
plant can be used as an ornamental. Even mosses, without true stem and leaf,
are employed in ornamental plantings, particularly in some Japanese gardens.
Ferns are frequently used as decorative plants in shaded or moist areas.
The coniferous plants (gymnosperms) are favorites used by nearly all peoples,
from the coldest to the warmest parts of the earth. In the temperate zones,
