The below search form provides access to the database of shared passages constructed for the
Digging into Data project. In all, we identified some 40 million shared passages using the
sequence alignment system. Single documents from the ECCO dataset were compared to every other document in the corpus and shared passages were collected and stored as pairs of matching passages, one being classed as “earlier” in relationship to the
other, “later” passage. We then compared these passages with several pre-18th-century collections, including EEBO-TCP and a collection of Greek and Latin texts, again storing the results as a matching pairs of passages (earlier and later uses). Users
can query all these pairs of passages either by looking for earlier passages (displayed on the left) or later passages (displayed on the right). One can, for example, search for all reuses of Cicero (in Author box on left) in the 1780s (1780-1789 in
date box on right); shared passages between John Locke (Author box on left) and Thomas Paine (Author box on right); or all the shared passages that appear in Voltaire’s works (Voltaire in Author box on the right).
