===================
General Information
===================

The raw data for TL-2 is available in two formats: Text and XML. Contained in this zip file 
are two folders of information, one for each format. In each folder are 15 files named
by TL-2 Volume or Supplemental Volume (e.g., TL_2_Vol_2.txt or TL_2_Suppl_7.xml).

The text files are separated by "PAGE" and "HEADING" headers and correspond to the pages of
content in the volumes that contain botanist information. Introductory and auxillary content
from the original volumes is not provided. The two indexes in each volume are also included 
in both Text and XML files, however they are unparsed in the XML files and may be of limited 
use.

The XML files are structured according to the provided taxonomic-literature.xsd. Generally,
Authors contain Sections of unparsed information and Titles of publications. Author names
are not parsed into subfields, whereas Titles of publications are nominally separated into
subfields.

Please be aware that as we continue to parse this data that these files are subject to
change in the future. The version number and date are indicated below to assist you in
identifying when new content is available.

Version: 1.3
Date: 29 April 2025

=================
TL-2 Authors file
=================
We also offer an export of the 9,914 author entries in TL-2. The fields included are:

  * NAME - Family name followed by given name(s) and/or given name variants. 
	  Example: Camus, AimÃ©e (Antoinette)
	* SURNAME - Only family name extracred from the Name field above.
	* TL-2 ABBREVIATION - Example: Camus or G. Eberle Please note, we have 
	  retained spaces in the abbreviation. Other databases (such as IPNI or 
		Wikipedia) may have removed them.
	* ALTERNATE TL-2 ABBREVIATION - In rare cases, an author was listed 
	  with a second abbreviation.
	* DATES - Any or all of the following: Birth year, death year, 
	  flourished year, etc.
	* DESCRIPTION - A brief description of the author as extracted 
	  from TL-2

Some authors are duplicated and will have an asterisk (*) beside the second
entry. This is due to TL-2 having been released with supplemental volumes that added
missing authors or expanded upon authors that were included in the original volumes. We 
have chosen to keep these entries separate due to the expanded descriptions the supplemental 
authors seem to have. In these cases, the TL-2 Abbreviation of the original entry (wthout the 
asterisk) is assumed to be identical to that of the supplemental entry (with the asterisk).

The Authors file is sorted by TL-2 Abbreviation.
