Specialised dictionaries (also referred to as technical dictionaries) focus on linguistic and factual matters relating to specific subject fields. A specialised dictionary may have a relatively broad coverage, e.g. a picture dictionary, in that it covers several subject fields such as science and technology (a multi-field dictionary), or their coverage may be more narrow, in that they cover one particular subject field such as law (a single-field dictionary) or even a specific sub-field such as contract law (a sub-field dictionary). Specialised dictionaries may be maximizing dictionaries, i.e. they attempt to achieve comprehensive coverage of the terms in the subject field concerned, or they may be minimizing dictionaries, i.e. they attempt to cover only a limited number of the specialised vocabulary concerned. Generally, multi-field dictionaries tend to be minimizing, whereas single-field and sub-field dictionaries tend to be maximizing. See also LSP dictionary.
