This week, in our Linux Page (in Spanish) we have posted a new ebook (in EPUB format) reader for Ubuntu: Lucidor. This software is not a simple ebook reader but it also allows you to search ebooks through an embedded search engine which is able to scan Google Books, epubcatalog.org, Lexcycle, Feedbook and – of course- your personal local library. Unfortunately, the Lucidor search engine does not support the Project Gutenberg that, we believe, at the moment, is the most interesting free project for ebooks. Lucidor is complex, well structured and flexible. To conclude we would also suggest another reader FBReader that has not any search engine but it manage very well the EPUB ebooks and offers very readable texts. Something to try!
