Having appropriate, up-to-date and accessible reference material is essential for the production of high-quality translations. Here are some of the reference materials I own and/or use regularly, in addition to hundreds of readily available resources online, e.g. ISOs, professional associations, government bodies, industrial associations, EU terminology databases, NGOs, etc.:

  • The IUPAC (International Union of Pure and Applied Chemistry) Gold Book, "Compendium of Chemical Terminology" - 1,670 pages of fundamental terminology

  • The IUPAC Green Book, "Glossary of Terms in Quantities and Units in Clinical Chemistry"

  • The EU English Style Guide for Translators

  • "Machinery's Handbook", 11th edition, The Machinery Publishing Company

  • From the European Medicines Agency*: QRD Templates, Preferred Terms, Undesirable Effects Numbering System, Decisions on Stylistic Matters, Notes on Pregnancy and Lactation, Adverse Reactions, Units and Measurements, Routes of Administration.

  • Dictionaries & Glossaries: "Spanish to English Technical Dictionary", Routledge. Indispensable source that covers dozens of fields, from agriculture to wave physics; "Oxford Dictionary of Chemistry", OUP; "Dictionary of Science and Technology", Newmark; "Oxford Medical Dictionary", OUP; "Diccionario Técnico Español - Inglés", García Díaz, Limusa; "Spanish/English Dictionary of Electricity and Electronics", Titus, Titus II & Gámez, Thomson; "English <> Spanish Technical - Scientific Dictionary, 3rd Edition", RCGlobal.

  • I have collected and compiled glossaries on civil engineering, pumps & pumping, concrete, drilling, plastics, rheology, flow dynamics and measurement, distillation, geotechnical surveying, wires and cables, aviation, histology, screen-printing and microbiology, amongst others.


* Although for translation purposes I always use the current editions, the EMA documents presented here may not be the most recent versions. Please refer to the EMA's website or contact me for more information.
