Taxonomy of Evaluation

"A wide range of models of PR and communication evaluation exist using a wide range of terms including inputs, outputs, outtakes, outflows, outgrowths, effects, results, and impact. An even wider range of metrics and methods for evaluation are proposed for each stage. The field is confusing for many practitioners. This page presents a taxonomy of evaluation tailored to strategic public communication – a taxonomy being a mapping of a field to produce a categorisation of concepts and terms – in short, to show where things go and where they fit in relation to each other.

London Library Classification Scheme

"The London Library has a unique and rather unorthodox classification scheme. Described as 'unusual but serviceable' by Alan Bell (Librarian of the London Library from 1993 to 2001), its application and maintenance are both a joy and a challenge. The scheme was devised by Sir Charles Theodore Hagberg Wright (1862-1940), Librarian of the London Library from 1893 until his death. (...): it was created on the principle of literary warrant, that is, it was designed around the books the Library held at the time.


"The HRCS is a system for classifying and analysing biomedical and health research funding. Its role is to faciliate research management by answering strategic questions about investment. (...) The Health Categories dimension of the HRCS captures the area of health or disease being studied. There are 21 separate categories which encompass all diseases, conditions and areas of health. (...) Research Activity Codes classify types of research activity.
