The database can be searched by scientific name, family, locality, collector and herbarium number and these are also the fields in the data returned. It is the result of a project initiated in 1997 and supported since 1999 by the Bank of Sweden Tercentenary Foundation. The Linnean herbarium holds some 4,000 specimens. The aim of the project is to present images of every sheet in the collection - currently 2121 are available online. Most of the content is in English, with some elements in French.
Some sections remain unfinished.
