In order for them to operate effectively several adaptations are made to the base texts before they are processed by the concordance software.

• All ampersands (&) have been converted to the word "and".
• The characters æ and Æ have been converted to ae and Ae respectively.
• As with all texts on this site, the long s has been converted to its modern equivalent.
• Because the texts are all HTML facsimiles, word spacing may interfere with concordance searching. For example: the conjunction "in'th" may appear in the text as in 'th and as in'th and as in'th'. All three will be indexed separately.
• The concordance requires as its base text a plain text document. Any italic or bold text has been normalised.
• In general, title pages are not included in the concordance.
• Any commendatory verses will be included in a separate concordance so as not to disturb the line numbering of the original poem or play.
