The Greek font that the Society of Biblical Literature has been developing is now complete and available for download.
Downloading and usage are free for non-commercial projects, but the font itself is not open-source. A list of open-source Greek fonts is available, however, as well as instructions for installing and using any of these unicode fonts under Windows, Mac, and Ubuntu.
For assistance with the SBL Greek and Hebrew fonts, you can also check the SBL font forum or email font support.
