BGBM specimen images should be cited as: Röpert, D. (Ed.) 2000- (continuously updated): Digital specimen images at the Herbarium Berolinense. - Published on the Internet http://ww2.bgbm.org/herbarium/default.cfm [accessed <date>]. For reference to an individual image, cite the barcode of the specimen as well as the image ID as shown on the image detail page.
Currently, as a rule only basic information is captured in textual form; i.e. the barcode, the scientific name under which the specimen is stored, the modern country of origin (where it can be easily deduced), and the original designation of the collection site. We are working on a procedure to allow remote annotation of the images.
