Read this: Eclectic readings also normally give an impression of the number of witnesses to each available reading. Although a reading supported by the majority of witnesses is frequently preferred, this does not follow automatically. For example, a second edition of a Shakespeare play may include an addition alluding to an event known to have happened between the two editions. Although nearly all subsequent manuscripts may have included the addition, textual critics may reconstruct the original without the addition.
