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.

F. Markgraf Review in Botanische Jahrbuecher
84(3) Lit. 13-14, 1965
(Botanischer Garten Zurich 39)

The author, like many botanists who had the opportunity to collect plants in Mexico and on attempting to identify them, found herself seriously hindered by the lack of a comprehensive flora. But she drew a positive conclusion from this and set about preparing the necessary compilation of the literature. In 24 years, she completed the work and, this alone, commands attention. Beyond the original goal of covering systematic and floristic works, also included were works on anatomy, embryology, cytology, genetics, useful plants, native plant names, exploration and travel, etc.

The work is arranged in the practical manner for which works from the U.S.A. are often admired. On the technical decisions, which the author must make, an explanation is given in the introduction. Her guiding thought was always the usefulness for the botanist. Some partly facetious remarks of other bibliographers precede the historical introduction. The objective advantage of the work rests on the short statements on the contents of the works (cited). The author has, with technical knowledge, herself gone through everything available. But she has made the evaluation even further: the enumeration, alphabetically by authors, supplements in 156 quarto pages in fine print, a subject index modestly designated an index, which contains the botanical and native plant names, place and personal names and subject cue words from the various fields of botany.

I believe that no user of the work will have any basis for using a sentence from the preliminary remarks: "The specialist tends rather to criticize than to praise", but rather will be generally received with appreciation.

Langmann, Ida Kaplan: A selected guide to the literature on the flowering plants of Mexico. — Philadelphia (Univ. Pennsylvania Press) 1964. 1015. S. 4°. Preis 25 $.

Der Verfasserin ist es gegangen wie vielen Botanikern, die in Mexiko Pflanzen sammeln und bei dem Versuch, sie zu bestimmen, durch das Fehlen einer zusammenfassenden Flora empfindlich behindert wurden. Sie hat daraus aber eine positive Folgerung gezogen und die notwendige Zusammenstellung der Literatur in Angriff genommen. In 24 Jahren hat sie dieses Werk vollendet, das allein schon durch seinen Umfang Achtung gebietet. Über das ursprüngliche Ziel hinaus sind außer systematischen und floristischen Arbeiten auch solche über Anatomie, Embryologie, Zytologie, Genetik, über Nutzpflanzen, einheimische Pflanzennamen, Forschungsreisen u. a. aufgenommen worden.

Das Werk ist in der praktischen Weise angelegt, die man oft an Arbeiten aus den USA bewundert. Über die technischen Entscheidungen, die die Verfasserin dabei treffen mußte, legt sie in der Einleitung Redensart ab. Im leitenden Gedanke war dabei immer die Benutzbarkeit für Botaniker. Einige zum Teil scherzhafte Bemerkungen anderer Bibliographen werden der historischen Einleitung vorangestellt.

Der sachliche Vorteil des Werkes besteht in den kurzen Angaben über den Inhalt der Arbeiten. Die Verfasserin hat zu diesem Zweck alles durchgesehen. Sie hat die Auswertung aber noch weiter getrieben: die Aufzählung, alphabetisch nach Autoren, ergänzt auf 156 Seiten Quart in Kleindruck ein bescheiden als Index bezeichnetes Sachregister, das botanische und einheimische Pflanzennamen, Orte- und Personennamen und sachliche Stichworte aus den verschiedenen Gebieten der Botanik enthält.

Ich glaube, daß kein Benutzer des Werkes Grund hat, einen Satz der Vor bemerkungen anzuwenden: "The specialist tends rather to criticize than to praise", sondern daß es allgemein mit Dankbarkeit aufgenommen werden wird.
