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.

KAPLAN LANGMAN, Ida Mrs. A selected guide to the literature on
the flowering plants of Mexico. - University of Pennsylvania Press, 3729
Spruce Str., Philadelphia, Pa.: 1016 pp. $25.--

This large volume contains the most comprehensive available bibli-
ography of the "flowering" plants (actually covers the seed plants or Sper-
matophyta) of the United States of Mexico from the 1500's up to the pre-
sent time. The idea for the work came to the authoress as a result of her
frustrated efforts at learning more about the Mexican flora from books and
journals. In her searching out of books and journals to incorporate in her
annotated listing, she visited 49 libraries in the USA alone as well as a
much greater number in Mexico. The guide proper runs by the alphabetic
sequence of authors' names, covering 793 double-columned pages (pp. 65-
857), which is followed by the thorough indexing of all items by subject mat-
ter. This latter index covers 157 four-columned pages (pp. 859-1015) and
is ordinarily the first part of the book consulted, unless one knows the name
of the author of some particular work. All botanical gen.names are listed
alphabetically under the fam. name. - The most complete coverage is in
the field of plant taxonomy and chorology (geography), with a considerable
amount on ethnobotany; the listing is also of course of interest to one in
the field of the history of science and botany. Data on the following more
limited fields are also contributed by this volume: vernacular names in the
indigenous languages of Mexico; biography; economic botany (as a broader
field than ethnobotany, since including modern industrial and other uses);
travel and descriptive works coming within the discipline of geography, when-
ever these make mention of the plants of the country. - Despite its great
size, the compilation seems to be relatively free from error.
