Curation and collection management

Preservation:

Most specimens are dry, some wet:

  • The Melvill-Tomlin Collection includes over 80,000 lots of dry shells.
  • The Spirit Mollusc Collection is stored in alcohol.
Database information:

60-70% of the collection is databased on Filemaker online, including:

  • 20,000 bivalves
  • 40,000 pulmonates (terrestrial gastropods)
  • 60,000 prosobranchs

The best use of the database is for finding historic (pre-1900) material. Searches can also be done using expedition name – for example there are 700 bivalves from expeditions, of which 52 are from HMS Challenger.
