Creating a Digital Herbarium using Voyager and ImageServer

The MBLWHOI Library Digital Herbariumwww.mbl.edu/herbarium/
• Specimen images and data freely available on Internet via fully searchable database
• Joint project with NEAS• Funded by WHOI Sea Grant

About the MBLWHOI Library Herbarium
• Originally part of the George M. Gray Museum• Roughly 8,000 specimens• Over 100 years of collecting• Documents flora of Cape Cod and the Islands• Recently moved to a new location – now part of the
MBLWHOI Library

A Valuable Collection
• Cape Cod a region of great botanical interest• Most of Massachusetts’ rare plants are found on
Cape Cod or in Connecticut River Valley• Nexus of cold northern waters and warm southern
waters – results in great marine algal species diversity

Why a Digital Herbarium?
• Rich searching capabilities - greatly facilitate the study of floristic and environmental changes over time
• Facilitate updating of records• Make the collection available to researchers
worldwide• Create an online compendium of the flora of Cape
Cod and the Islands• Contribute towards preservation of the collection

Digitizing Herbarium Specimens
• Epson Expression 1640XL Graphic Arts scanner• Scanner inverted with custom built stand• Camera/copystand for delicate specimens

Image Specifications
• Entire sheet scanned into PhotoShop at 600 ppi• Creates 7000 pixel, ~200 MB TIFF• Resized to 960 pixel, ~200 KB JPEG for web• 960 width gives a good overall impression of the
entire herbarium sheet • Portions of original hi-res TIFF selected for detail
images

Homegrown Database vs. Voyager
• Voyager is stable and supported by EISI• Already running Voyager and know how to use it• Other projects have used Voyager• MARC, which is familiar, could be used to catalog
Herbarium specimens• Could be paired with ImageServer, which we also
have already

ImageServer• JPEGs are filed on the server via ImageServer• Images are associated with data from the
herbarium sheets• ImageServer client communicates with Voyager
Cataloging client on the same workstation• Cataloging creates a skeletal MARC record
containing a link to the associated images

Full Cataloging of Herbarium Specimens
• The Herbarium database is separate from the main Library catalog
• The record is fleshed out by a cataloger• More than 50 data elements are possible• Uses MARC adapted to Herbarium specimen data• MARC tag tables have been edited for herbarium
data – fields and subfields re-labeled for ease of cataloging
• The headings in public display are tailored to Herbarium data

HerbMARC Examples• 245 Title = Current Species Name• 246 Varying Form of Title = Common Name• 247 Former Title = Synonyms• 100 Author/Creator = Collector• 700 Added Entry-Personal Name = Additional
Collectors/Determiners, etc.• 651 Geographic Names = Locations

Workflow• 7 volunteers scan specimens, creating tiff and jpeg
images of full herbarium sheet• Volunteers then link the images to brief data in
ImageServer• Project staff create detail images from the original
tiffs • Project staff perform full cataloging of specimens

Where We Are – March 2005
• Project began in December 2002 with marine algae• 1200 specimens scanned• 400 full records

How to make your image be the hot link to itself
• Use a separate image as the hotlink:– 856 7 $2 sdc $f 3,669,1 $z <img src=
"http://herbarium.whoi.edu/cgi-bin/Pscandoc.cgi?app=3&folder=669&doc=2">
• Have ImageServer generate a thumbnail:– 856 7 $2 sdc $f 3,669,1 $z <img src=
"http://herbarium.whoi.edu/cgi-bin/Pscandoc.cgi?app=3&folder=669&doc=1&size=1">
