The term 'dictionary' for a layman means a reference book that consists of a list of words along with their meanings. And, when one talks of a dictionary, he or she is implicity understood as referring to a dictionary of English words. But, unlike what our minds are turned to think, a person who is talking about a dictionary might just be talking about a glossary of terms belonging to a particular subject. This is exactly where our series comes in the picture. The series consists of dictionaries on varied subjects, ranging from common topics like Commerce and Botany, to very profound and complicated subjects like Entomology and Toxicology. The use of simple and easily comprehensible language, along with real life examples and approproate pictures, fosters an enriching learning experience for the readers, therby making each and every volume a must buy.
