All articles in Zoological Record (1864 to 2012) found with the Systematics search terms 'Revision' or 'New taxa' or 'Diagnosis' or 'Description' or 'Taxonomy' sorted by journal. Search returns nearly 200,000 articles but results are strongly concentrated by journal. So XML markup of the legacy content of the top 27, 107, and 311 ranked journals would respectively cover 25, 50, and 75% of all taxonomic articles in Zoology. Progress toward marking up the long tail of articles published in journals with relatively few taxonomic papers each would be approached by a distributed network of self-motivated individuals using the next generation of markup software.
