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.

But the seedlings so abundant throughout the tropics do not
represent this fruit at its best. While of good flavour, they are
commonly characterised by coarse fibres throughout the flesh which
makes eating an annoying process. In contrast, the fine grafted
varieties which have originated in India and a few other regions,
as well as seedlings of the excellent race cultivated in the
Philippines as well as in several other parts of southeast Asia (known as Manila in Mexico and Filipino in Cuba) are almost devoid of fibre and of excellent quality.

In 1889 the U.S. Department of Agriculture introduced into
Florida the first of the grafted East Indian mangoes to be known in
this country, the variety Mulgoba. In subsequent years, mainly
through the efforts of Reasoner Brothers and of David Fairchild,
more than fifty other varieties were brought to the U.S., whence their cultivation gradually spread to many parts of the American tropics. Some of the best of these are Pairi (known as Bombay in Jamaica), Borsha, Amini. In addition to these such varieties as Carabao from the Philippines and Saigon from Cambodia should be mentioned, as well as Julie which first received horticultural attention in the French West Indies and has become popular in Jamaica and elsewhere. Due to the failure of many of the best varieties to produce regular and heavy crops of fruit, they have been replaced in commercial orchards by Haden (a seedling of Mulgoba which originated in Florida) and others which have recently been developed in this part of the world.

Mango trees are injured by a few degrees of frost. They are successfully grown commercially in southern Florida, but they have not been wholly successful in California, though occasional trees have fruited in that state. The mango is not particular as to soil, but the finer varieties only produce fruit abundantly where there is a well marked dry season to stimulate production of fruit rather than continued vegetative growth. There is another serious problem in rainy areas: a fungous disease known as anthracnose (Colletotrichum) which destroys the flowers and young fruits and is expensive to control.

Propagation of the better varieties is by means of grafting or budding. Inarching is widely practiced in tropical Asia, but is
