An SCP concordance consists of a keyword followed by a series of citations which show how that keyword is used. Alongside the context is a reference to where in the text the word appears. You can choose to have the keyword centred within the context or to display the line in which the word occurs.
You can sort the centralised citations according the context that appears to the left or right of the keyword.
You can produce a concordance of a chosen word or all words that have a given prefix, suffix, or contain some particular letters. By selecting keywords you can choose a particular subset of the vocabulary used, which can be pre-sorted before a concordance is produced.
