Sometimes it seems that every field wants its own informatics subfield. For example, in the health and medicine arena, you might come across health informatics, consumer health informatics, community health informatics, public health informatics, disease informatics, medical informatics, clinical Informatics, nursing informatics, dental informatics, translational bioinformatics, medical imaging informatics, and the list goes on. But it isn't only health and medicine that have gotten on the informatics bandwagon. You might also come across museum informatics, business informatics, cheminformatics, education informatics, environmental informatics, legal informatics, music informatics, and on and on.
Since it's so popular, it would be good to find out just exactly what informatics is. (Good luck with that endeavor!) But, of course, informatics isn't something that occurs in nature, whose nature can be discovered. Informatics is a label put on a set of perspectives, activities, phenomena etc., found useful in some context and varying across contexts. The range of activities/phenomena belonging under the informatics umbrella is quite broad, including, inter alia, clinical decision support systems, interoperable electronic health records, identifying a consensus classification of biological organisms, the simulation of neural systems of specific animals, virtual screening of large libraries of chemical compounds, magnetic resonance imaging, in-car navigation systems, case-based legal prediction, optical music recognition, etc. What all versions of informatics share is a focus on the interaction of information and computation.
In the DDC, informatics is mentioned in the schedules in two places: 004 Computer science (indexed by the Relative Index heading "Informatics—computer science") and 020 Library and information sciences (indexed by the Relative Index heading "Informatics—information science"). No interdisciplinary number for informatics has been identified, since works on informatics almost invariably treat the informatics of specific fields. The point of listing informatics in the class-here notes at 004 and 020 is to motivate the giving, at both locations, of the following scatter class-elsewhere note: "Class informatics of a specific subject with the subject, plus notation T1—0285, e.g., bioinformatics 570.285."
Accordingly, we find the following titles on the informatics of specific subjects classed in the Dewey numbers indicated:
