Collins Dictionary of Biology
The bestselling edition of the Collins Dictionary of Biology is designed for advanced school students, undergraduates and all who have an interest in the life sciences, from recent advances in genetics to theories of evolution. It includes over 6,500 entries, with many helpful illustrations, covering all of the major fields within biology - including anatomy, biochemistry, ecology, evolutionary theory, genetics, molecular biology, physiology and taxonomy. The dictionary also includes descriptions of techniques and tests commonly used in biology, as well as statistical terms.

Dictionary of Astronomy, Peter Collin Publishing
A comprehensive dictionary, covering all aspects of astronomy, from telescopes to planets, stars to comets. The dictionary contains over 1,700 terms, clearly explains complex terms, and has been fully revised and updated to include the latest missions, discoveries and equipment.
A wide range of sources has been used in the compilation of this Dictionary, including books, journals and magazines as well as press information from such bodies as the European Space Agency, NASA and PPARC in the UK. Among magazine sources, it is essential to acknowledge Sky and Telescope, based in Cambridge, Massachusetts, which is simply the one-stop source for up to date astronomy information and which was invaluable in the updating of my own text. The books listed here were all useful, but Jay M Pasachoff's Contemporary Astronomy and its companion volume, Astronomy: From the Earth to the Universe, were especially valuable and the data on the brightest and nearest stars comes from them.
Astronomers use online resources extensively. Sites worth a look because of their extensive links to other astronomy content include: Sky and Telescope at www.skypub.com: a lengthy list of astronomy sites run by the Carnegie Institute of Washington at www.ciw.edu/Astro_hot.html: the (UK) Royal Astronomical Society, www.ras.org.uk: and for space missions, NASA, www.nasa.gov and the European Space Agency, www.esa.int.

Dictionary of Developmental Biology and Embryology, Wiley
Developmental biology is the study of the mechanisms of development, differentiation, and growth in animals and plants at the molecular, cellular, and genetic levels. The discipline has gained prominence in part due to new interdisciplinary approaches and advances in technology, which have led to the rapid emergence of new concepts and words. The Dictionary of Developmental Biology and Embryology is the first comprehensive reference focused on the terms, research, history, and people of this field.
This authoritative A-to-Z resource covers classical morphological and cytological terms along with those from modern genetics and molecular biology. Extensively cross-referenced, the Dictionary includes definitions of terms, explanations of concepts, and biographies of historical figures. Comparative aspects are described in order to provide a sense of the evolution of structures. All features of embryology and developmental biology are covered, including:
• Vertebrates
• Invertebrates
• Developmental genetics
• Medical embryology

Illustrated Dictionary of Science, Andromeda
The Illustrated Dictionary of Science is a well-organized dictionary of science covering all the major scientific disciplines: physics, chemistry, biology, ecology, medicine and physiology, and the Earth sciences (e.g. Polaris, retrovirus, trephine, vapor). Its entries also explain terms belonging to the history of science and include brief biographies of important scientists (e.g. Curie).
Diagrams and artworks illustrate key concepts of science, making the dictionary particularly suitable for use in the classroom or as family reference. The lavishly illustrated entries explaining such topics as the solar system, plant evolution, skeletons and muscles, or geological time scale are a unique feature of this dictionary.

The New Penguin Dictionary of Science
"When writing about science, I have a parrot perched on my shoulder who cries out every so often in his raucous voice, 'Can this not be said more simply' The authors of this dictionary have clearly followed my recipe...the definitions [are] concise, rigorous and lucid." - Max Perutz
