Portable TomeRaider v3.3.9 is an advanced ebook reader for the PC (non-windows versions are available at www.tomeraider.com).
It supports images, tables, full-text search ... and utilizes efficient data compression, allowing for relatively small ebook sizes. There are hundreds of free ebooks available from within the app (click on the world icon) or online at www.tomeraider.com. Examples of ebooks include IMDB, wikipedia, dictionaries & the complete works of Shakespeare.
This app was made portable using Thinstall, which means it can be run from a USB drive without first installing and with all settings maintained (a TRSettings folder is created on first use).
