Welcome to TL-2 Online, the online edition of Taxonomic Literature, 2nd edition (TL-2).
TL-2 is the standard reference work for plant taxonomic literature from Linnean times to 1940. In the field of plant taxonomy, detailed information of particular publication dates is often critical in deciding matters of nomenclatural priority. With the many complexities of botanical and plant taxonomic publications that often were published in parts over periods of months if not years or decades, providing these bibliographic and publication data was a formidable task.
It took Frans A. Stafleu (1921-1997) and Richard S. Cowan (1921-1997) fourteen years (from 1973 to 1988) to compile the original seven volumes and later Frans Stafleu and Erik Mennega (1923-1998) six years to add six supplements to the series.
In this online edition you can browse the volumes and supplements of TL-2, and the original work is enhanced by the addition of various search options, including full text searching. Many of the works that were analyzed in TL-2 are available in microform and reprint editions from IDC publishers and can be ordered directly from the website.
IDC Publishers is proud to present this online edition, and we would like to thank the International Association for Plant Taxonomy (IAPT) for its generous support.
