Is there a name for an obviously erroneous duplication of a word in a print medium? For example (with apologies to Mr. Lincoln)" "Four-score and seven seven years ago..." If someone is relatively certain there isn't one, can you suggest a suitable short "title" for a list of such cases?
As StoneyB writes, this is a dittography, Oxford dictionary says:
A mistaken repetition of a letter, word, or phrase by a copyist.
Origin: Late 19th century: from Greek dittos ‘double’ + -graphy.
It is not clear how technical a description you want, you should give a little more details of the context in which you'll refer to these typos. You could use 'List of dittographies', or 'List of erroneous repetitions'.
