External references have been completed and a partial but significant number of definitions have been created.

The Universal Pages shows all possible terms attached to a specific unit in all languages of the terminology. These pages will be progressively generated for all units. A sample is visible for musculus digastricus at URL "../auto/univ/EN/TAH1747 Universal EN.htm" (direct access: universal|EN|1747). The corresponding help file is also available.

A systematic upload of all Latin/English Unit pages has been undertaken, concerning the TA98 entities being implied in the TNA chapters. These pages may have errors or missing parts like the definition or the taxonomic hierarchy. A systematic validation of all Unit pages has not yet been performed.

This section has been largely redesigned. Progressively, the TA98 website is inserted within the current website. The principal new feature is the availability of tables for each chapter with the integral content of TA98 source edition. The trace option, from TA98 to TNA, is in development and will be added progressively to all chapters concerned by TNA.
