Free software intended by our community is the one defined by The GNU Project related to freedom unrelated to price. To avoid ambiguity and confusion, the word free is often omitted with libre, hence libre software, to explain that free software is free as in freedom not price. Please read Free Software Definition for further explanation. However, in reality there are many uses of libre in multiple projects and communities and even in the name of several free software applications. We will examine them in this list.

"  Their book sources are the public domain ones and their providers are Internet Archive and Gutenberg Project.



To sum it up, apparently there are many free software with libre as in names other than LibreOffice as the most popular one. These 30+ names are all I can collect for today and of course they may increase or decrease over the time. We can watch these projects growing, use the software or service, share, improve, or even fund and contribute to them.
