Adobe Systems has released a new version of its Mac beta eBook Reader.

Like its predecessor, version 2.1 incorporates CoolType customisable-font management. The eBook Reader now also supports a two-page layout feature. Adobe has added a new feature – it's possible to click on a word in the viewer to look it up in its interactive dictionary.

The eBook beta-reader requires Mac OS 9.0 or 9.1, 256 colours displayed, QuickTime version 4 or later, and a Web browser.

It's available now as a free download from Adobe.
