What's Here and What's New

This World Wide Web site is intended primarily to provide information on IUBMB and IUPAC nomenclature recommendations. The full text version of documents will be converted into a Web readable form which may also involve some reorganisation to facilitate presentation. As the author has been primarily involved in the preparation of organic and biochemical material most work will be in that field. Other material will be provided as it becomes available, either from this site or by links to other locations.

I am also preparing a list of all translations of IUPAC nomenclature recommendations. While I can identify many, I have only limited access to journals published in languages other than the main European languages. Likewise translations of the IUPAC nomenclature books are not readily available to me. Anyone able to help me with additional translations please contact me by e-mail at g.p.moss@qmul.ac.uk
