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.

Page transcription

does not turn yellow. This has the advantage that the text can be finished at
the same time as the specimen. If the text is printed, much necessary time is lost
and, if the descriptive matter is lagging, it is difficult to catch up with matters neglected. It would be most advantageous if the text could be glued to the show-glass, even if it were done only with the "art-corner", used in photographic albums. All my efforts to fasten durably paper on glass were in vain. After a longer or shorter time it became loose again. If the text is placed directly in front of the specimen, the danger exists that it may get lost or be changed by mistake.

Other objects of demonstration which should not be absent from a botanical museum's exhibition, are window-diapositives (these may be illuminated artificially), or photographic pictures of plants which have been taken on the spot in the natural surroundings. Thus pictures of Cacti and succulent Euphorbiaceae which exist half buried in sand, should be shown. One may present pictures of epiphytes which are taken in the primeval forests. The different museums of natural science possess such pictures also in colors. In addition stereoscopic pictures of characteristic landscapes are important, like steppes, savannahs, primeval forests, mountain ranges, especially colorchromes of this country. There are stereoscopic machines which the visitor may operate himself, without being in the position to touch the picture itself. Microscopes also may be set up, safe against vandalism, to show interesting microspecimen by means of revolving object tables. I saw this very well in the Newark Museum in Newark, N.J. In plant physiology and in genetics it may be difficult to manage without reproductions from books. Also demonstrating apparatus should be necessary. As I mentioned for artists would be a field of action, e.g., a model of the method to receive polyploids by using colchicine, after Blakeslee, would be very interesting.

The wet and dry preparations must be kept in show cases. These cases should be preferably of metal and must be shut dust tight. They should not be too high, so that specimens standing high up, may be studied also. Large and heavy objects are, of course, placed in the lowest compartment of the case. For shelves in the case we had cut glass plates which were reinforced by iron rails (angle iron).
