Since 2003, data concerning material, slides and taxa, existing within the Friedrich Hustedt Diatom centre, are being entered in a database. In 2014, all data from the initial collection database have been transferred into a new system using the EarthCape platform. The web interface of this new system is now on-line but is incomplete. The database stores information on all specimens in the collection, named by Hustedt or deposited later by other workers, with the literature-, material- and slide-information. Taxon names have been entered as they appear on the slides or on a sheet in a slidebox, although in some cases, recently proposed names are given under “comments”. The database also has a complete entry of all of the publications held in the library of the centre, now more than 8,000.
