Discworld fans have a Mac-based treat with the release of Pratchettes 2.0 for OS X.

It's the first time Pratchettes has been available for Mac OS X. The application is a 4,600-strong database collection of Terry Pratchett quotes. It's searchable and users can add new material if they like.

The application includes a full Pratchett biography and bibliography as well as a "whimsical description of the magical Discworld itself, mostly in Terry Pratchett's own words", the developer said. There's also a digital version of the "Discworld Map".

Pratchett's Discworld novels have sold over 50 million copies worldwide.

The Pratchettes Terry Pratchett quote database is driven by Panorama from ProVUE Development. The database application has only recently been converted to run natively on Mac OS X.
