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.

coast of Bombay (India) it is said that they must have a shelter belt to protect them from salt injury. Rainfall ranging from 30 to as much as 120 inches has proved satisfactory. While growth and production are best on well-drained soils, long periods of standing water are tolerated.

Propagation

Usually sapodilla trees are grown from seeds, which, if fresh, germinate in about 30 days. They can be stored for several months without losing viability. Some seedlings produce larger fruits or bear heavier crops than others, and these can be multiplied by vegetative propagation. The ponderosa variety in the Philippines and the Russell in Florida have very large fruits, while the Prolific variety of Florida is notable for consistently heavy crops of medium-sized fruits. In both India and the Philippines, amateurs have found approach-grafting on 1-year-old stocks successful, while professional propagators have reported 90% of success with cleft-grafting on 2-year-old seedlings. In Florida, where nurserymen consider vegetative propagation of the sapodilla difficult, veneer-grafting on 1-year-old stocks has given fair results. Except in early spring, it is desirable to girdle the scions about a month before using them, to assure an adequate store of food. It is wise to make a cut through the bark of the stock plant a little above the point where the graft is to be made, to drain the bark of latex which would prove troublesome when grafting, by forming a waterproof layer between stock and scion. Air-layering or marcottage is much used in India, requiring about 6 months before the marcot can be cut off and potted. However, some varieties are not easy to root.

Culture

Trees may be planted 25 to 40 feet apart, depending on the fertility of the land. Nursery trees are usually grown in containers
