QuotationFinder is a program for automated text comparison. It provides an efficient way to find intertextual references, such as citations, plagiarism and allusions. One text may be compared to a whole collection of texts, searching not only for all matching clauses or subclauses, but also for n-Grams. Since version 0.4.2 QuotationFinder has a facility to compare all pairs in a text collection to each other. Up to twenty-four statistical measures are calculated, reflecting how similar the document pairs are on word, trigram, subclause and clause level.

QuotationFinder is currently still under development. A beta version has already been tested internally and is available for download here. We are currently cooperating with a number of partner projects from the Cluster of Excellence 'Asia and Europe' which help us to test and optimize the program. The QuotationFinder will offer support to all established and new Cluster projects who show an interest in its use. As one precondition for working with the QuotationFinder is the digitization of the texts that are to be analyzed, we also introduced OCR (Optical Character Recognition) software to the Cluster.

From 2006 to 2007 the development of QuotationFinder was supported by a Karl-Steinbuch-Scholarship of the MFG-Foundation Baden-W├╝rttemberg. Since December 2007 the project has been further developed as a part of the Heidelberg Research Architecture of the Cluster of Excellence Asia and Europe in a Global Context.
