Once a suitable text
A list of relevant texts will appear below, selected from
the 4.5 million public domain works in Hathi based on how closely
their vocabulary matches your query.
In my testing, this returns extremely relevant texts--usually
copies of the same work first, followed by other texts with a
similar subject matter.
The resulting matches are useful in a wide variety of application: building up a personal workset for HathiTrust, for example, or finding books that are similar to any reference text. You could use this same technology to build a browser plugin that would find related books for any news article you were reading on the Internet.
