Kew Herbarium Guesstimated
– 7 million specimens– 250,000 types
Less than 5% specimens databased
A variety of personal databases

Preparation for Digitisation
Computerise transactions Agree and document policy and
procedures Establish core fields (HISPID
pending ABCD) Develop hardware and software
infrastructure (e.g. catalogue database, mass storage)

Digitisation Strategy Curators to barcode, database and
image types for loan Repatriation & research projects
– to use infrastructure and core fields– data to be imported into Catalogue
(eventually) Pursue digitisation projects

Specimen imaging Decision to try to match
Cibachrome prints in terms of quality (e.g. suitable for many diagnostic purposes)– 600 dpi delivers 200MB images
Stored as uncompressed (but bzipped) TIFFs
Acquisition of mass storage

HerbScan
A3 flatbed scanner, inverted
Cradle for specimens
Distributed throughout Herbarium

Pros and cons
£30-40,000 200MB images
barely achievable 1 image per minute Fixed Versatile
£7,500 200MB images
easily achievable 10 images per hour Some mobility Suited to flat items
200 MB master images (600 dpi scans), based on capturing the level of detail of Cibachromes.

Web documents indexed using Lucene Flora Zambesiaca digitised and marked-up
with XML Experimentation with options for query and
output via Java servlet– using XSL to output selections– using Lucene to index the XML– importing the XML into a database
Other texts - jury still out, but Lucene route looks promising

Future
More data sources, including texts and images
Hierarchical browsing front-end based around revamped Brummitt Families & Genera with phylogenetic classification
Looking forward to – using the GBIF Names Service…– links with DiGIR/BioCASE resources...
