I am going through the motions of this now, and Yes, the ebgaramond package provides this interesting font. The only issue I am having with it is that it lacks a bold font. This is not necessarily a bad thing as exemplified by Egregs comments in: https://tex.stackexchange.com/a/161675/4621
There are solutions to 'the bold problem' which I am working through now, only because I am retrofitting a document. The solution is given here: EBGaramond Bold
The Licensing as laid out by the author is:
EB Garamond is free software under the terms of the SIL Open Fonts License (ofl). That means, you are entitled to do what you want to with these fonts, as long as you
- retain the ofl notice, even if you distribute it in a modified form
- don’t sell them on their own
- don’t claim they were your work.
There is no pdf manual as such, and I am still confused by some of the terms, still, blind leading the blind here is a MWE to get you started. Lining gives me proper numbers again.
\documentclass{scrbook} \usepackage[lining]{ebgaramond} \usepackage{lipsum} \addtokomafont{disposition}{\rmfamily} \author{\swshape Authors Illustrious Name} \title{Title} \date{} \begin{document} \maketitle \chapter{In the Beginning} \lipsum[2] Some numbers and interesting ligatures ff, ffi, st, 123456789 \end{document}

ebgaramondis subject to The SIL Open Font License (OFL), which states: "The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves." So as long as you are not selling the font itself, you are OK.
