I love volunteering for the Biodiversity Heritage Library. I taxo tag images in the BHL Flickr account. This assists the use of these images by BHL as well as other institutions that use BHL content. It is also my favorite way of exploring BHL. I get a real thrill out of the serendipitous discoveries I make while tagging. My most recent BHL adventure resulted from tagging an album of images from the boringly named but absolutely fabulous Botany of the Antarctic voyage of H. M. discovery ships Erebus and Terror in the years 1839-1843.
