Digitization of herbarium specimens and related materials includes the capturing of data and images, and storing them in a digital format. Considerable progress has been made in the creation of digital assets from herbarium collections as well as in the dissemination of this information. The digitization process allows for collections to be queried and analyzed in ways not previously possible, and enables virtual access to those unable to visit the collections in person.
Below are details of our various digitization projects.
Indiana Memory Digitization - The Eli Lilly & Co. Collection (2014 - 2015)
The Indiana Memory Project is a collaborative effort to provide access to the wealth of primary sources in Indiana libraries, archives, museums, and other cultural institutions, made possible by the U.S. Institute of Museum and Library Services, administered by the Indiana State Library. The Kriebel Herbarium joined this project in 2014 and have since digitized our Herbarium correspondence collection. These documents contain many letters between important faculty of the Department of Botany and Plant Pathology at Purdue as well as documents detailing some of the collections within the Herbaria. Our correspondence collection is available via Purdue E-Archives.
We are currently working on digitizing one of the most important collections in the Kriebel, the Eli Lilly & Co. Pharmaceuticals collection. To learn more about this collection, see our "Important Collections" of the Kriebel page.

The Macrofungi Collection Consortium (2014 - 2015)
The MaCC: Unlocking a Biodiversity Resource for Understanding Biotic Interactions, Nutrient Cycling and Human Affairs
Go directly to: Kriebel Herbarium's Macrofungi Collection
Mushrooms and related fungi (macrofungi) play a critical role in the lives of plants and animals, including humans, yet their diversity is underestimated. Understanding this diversity will be critical in analyzing impacts of habitat change, nutrient cycling in ecosystems, and distributions and diversity of host organisms. Scientists in the U.S. have been studying these fungi for the past 150 years, resulting in the creation of approximately 1.4 million specimens across 35 institutions in 24 states. These institutions joined in an effort to digitize and share online all data associated with macrofungi specimens. The resulting resource enables a national census of macrofungi and allow researchers to better understand the diversity of these organisms and the relationships between macrofungi and other organisms.
The Kriebel Herbarium joined the MaCC in 2014 and has digitized all 260 catalogued specimens of macrofungi. These are available on MycoPortal and includes images of the label and the specimen as well as geolocation data.
Global Plants Initiative (2013 - 2014)
Go directly to:
Arthur Fungarium's Rust Fungi Type Collection
Kriebel Herbarium's Eli Lilly & Co. Pharmaceuticals Type Collection
Global Plants is a community-contributed database that features more than two million high resolution plant type specimen images and other foundational materials from the collections of hundreds of herbaria around the world. It is an essential resource for institutions supporting research and teaching in botany, ecology, and conservation studies. Through Global Plants, herbaria can share specimens, experts can determine and update names, students can discover and learn about plants and fungi, and a record of plant life can be preserved for future generations.
More information about the GPI can be found on the Global Plants About Page, along with Purdue's Partner Page.
A total of 397 type specimens of vascular plants from the Eli Lilly Collection at the Kriebel Herbarium were recently databased and imaged in 2012 as part of the Global Plants Initiative. They can be found on JSTOR's GPI site (institutional access required).
The Arthur Fungarium joined the GPI in June of 2013 to digitize the ca. 4000 type specimens in PUR. The digitization process was managed by Dr. Jordan Bailey, who supervised a team of undergraduate employees who conducted data capture as well as verification of type status. Specimens were scanned using the specially designed HerbScan system fabricated by Kew Botanic Gardens in London, England. The HerbScan is an inverted flatbed scanner house above a movable platform (see below). This platform is made of a foam base which absorbs pressure and avoids damage to specimens. Specimens were scanned at 600 dpi, which captures an amazing amount of detail, seen below in an example of Arthur Fungarium specimen. More specimen images from the Arthur Fungarium can be found on JSTOR (institutional access required).
