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.

(Travel and Descriptive)
WORKS PRIOR TO 1800 USEFUL FOR STUDIES IN MEXICAN BOTANY
Ida K. LANGMAN

THE following bibliography is part of a larger work now in preparation, to be entitled A Selected Guide to the Literature on Mexican Flowering Plants. This will list works in the fields of taxonomy (the identification and classification of plants), in economic botany (on uses of these plants by man), and in phytogeography (on the distribution of the plants and their ecology). It will include also works on the history of botany in Mexico, travel and descriptive works, vocabularies with names of Mexican plants, and botanical texts published in Mexico. The excerpt which follows lists travel and descriptive works, written before 1800, which include references to Mexican plants. Some are limited to the American area; others cover the entire world, as then known. Titles referring to the same period, but which are limited to Mexico, will be published, it is planned, in a later issue. Works whose primary emphasis is on natural history (Monardes, Hernández, etc.) are not included.

Most of the titles cited here are familiar to the student of Latin American history; many of them are classics in their field. But they are equally important to the botanist, for in them we find many of our first references to the plants of the New World in general, and of Mexico in particular. Yet most of these works were not cited by Nicolás León, in his Biblioteca Botánico-Mexicana.2 The works cited by León are preceded by an asterisk.

All of the works listed are available in the United States, and were seen, for the most part, in libraries in Philadelphia, New York and Washington. In most cases, the edition cited first is the one seen. Information on editions not seen has been added from various catalogues and bibliographies, especially the catalogue of the Library of Congress in Washington. This is abbreviated DLC. The letters RPJCB refer to the John Carter Brown Library in Providence, Rhode Island.

1 A preliminary listing of such works was published as "Ensayo para una bibliografía histórico-biográfica de la botánica en México," in the Memorias de la Academia Nacional de Ciencias de México, 57: 373-429, 1955.
