A while ago, I made a program which can be used for detecting strings
shared by two texts. It works under Unix and takes two filenames as
arguments. The output is a list of shared strings ordered by length,
with information on the occurrences in each text. Strings are only
listed if they appear with a variable context (e.g. "with respect to"
would only appear if it is preceded/followed by different words in the
texts). A shared string may also be a very large text block, in case
of very similar texts.
If you think this is useful, I can send you a copy of the program.

Cheers,

Tom
