Plagiarism Detection Software

http://www.iplagiarismcheck.com/I'm interested in recommendations for software that detects plagiarism.

I did see the note about etBLAST on the WAME listserve discussion in 2005, but wonder if there is anything else out there that people like.

Comments on how well etBLAST works are of interest as well.

eTBLAST only works on abstracts, so it isn't much use for plagiarism detection. It is better for spotting suspected duplicate publication. I use a similar tool to eTBLAST, JANE (Journal/Author Name Estimator), as it is much, much quicker. I find eTBLAST to be too slow. JANE is almost instantaneous, easy to use and has a nice looking interface: http://biosemantics.org/jane/

CrossCheck from CrossRef is a plagiarism detection service: http://www.crossref.org/crosscheck.html.

An easy way to check suspected plagiarism is to take a couple of phrases from the start of a paragraph or two and paste them into Google Scholar. That works if you get a "spidey sense" of plagiarism—font changes, changes in tone, paragraphs written much better than the rest of the article. I spotted one a fortnight ago by this method, but it is no substitute for automated checking.

eTBlast cannot find many obvious plagiarized texts. I compared it with Google and found that Google (as a free software) is much more reliable and is an overall good choice.
