Linux Libertine

Linux Libertine is a proportional serif typeface inspired by 19th century book type and is intended as a replacement for the Times font family.

The typeface has five styles: regular, bold, italic, bold italic, and small capitals, all of which are available in TrueType and OpenType format, as well as in source code. The OpenType version allows automatic positioning and substitution, including true fractions, ligatures and kerning. A display type variant, while similar in letter form, is lighter in weight and bears a closer resemblance to old-style types such as Palatino.

There is also a complementary humanist sans-serif face, Linux Biolinum, similar to Optima or Candara. It is available in bold and italic styles.

Linux Libertine contains more than 2,000 glyphs and encompasses character sets such as the Greek Alphabet, Cyrillic script, and Hebrew alphabet. Additionally, it offers several ligatures (such as f{{zwnj}}f, f{{zwnj}}i, and c{{zwnj}}t, and the capital ß). It also includes special characters such as International Phonetic Alphabet, arrows, floral symbols, Roman numbers, text figures, and small caps. The Tux mascot is included at the Unicode Private Use Area code point U+E000.

In 2010, Linux Libertine was adopted as an open-source substitute for the Hoefler Text typeface in the redesign of the Wikipedia logo, making it possible to localize the Wikipedia identity into more than 250 languages and character sets.{{cite news |url=http://blog.wikimedia.org/2010/05/13/wikipedia-in-3d/ |first=Jay |last=Walsh | work=Wikimedia Blog |title=Wikipedia in 3D |date=May 13, 2010| access-date=February 20, 2012}} The "W" character, which had previously been used in various other places in Wikipedia (such as the favicon) and was a "distinctive part of the Wikipedia brand", had "crossed" V glyphs in the original logo, while Linux Libertine has a joined W letter shape. As a solution, the "crossed" W was added to Linux Libertine as an OpenType variant.{{cite news|url=http://www.linuxlibertine.org/index.php?id=2&L=1|title=New Wikipedia-Logo using LinuxLibertine|last=Poll|first=Philipp H.|access-date=2011-01-30|archive-url=https://web.archive.org/web/20120320083529/http://www.linuxlibertine.org/index.php?id=2&L=1|archive-date=2012-03-20|publisher=Libertine Open Fonts Project}}{{cite news |url=https://wikimediafoundation.org/w/index.php?title=Wikimedia_official_marks/About_the_official_Marks&oldid=46774|first=Jay |last=Walsh | work=Wikimedia Foundation |title=Wikimedia official marks/About the official Marks|date=May 13, 2010| access-date=February 20, 2012}}

Both the Linux Libertine and Linux Biolinum typefaces are used by the open-source design publication Libre Graphics Magazine and the Association for Computing Machinery journals and conference proceedings.{{cite journal |last1=Carvalho |first1=Ana Isabel |last2=coons |first2=ginger |last3=Lafuente |first3=Ricardo |year=2010 |issn=1925-1416 |title=Production Colophon |journal=Libre Graphics Magazine |volume=1 |issue=1 |page=7 |url=http://libregraphicsmag.com/files/libregraphicsmag_1.1_lowquality.pdf |access-date=2011-07-18 }}{{cite book |last=Veytsman |first=Boris |date=November 5, 2023 |title=LaTeX Class for the Association for Computing Machinery |url=https://portalparts.acm.org/hippo/latex_templates/acmart.pdf |publisher=Association for Computing Machinery}}

László Németh created a variant of fonts with additional Graphite font tables: Linux Libertine G and Linux Biolinum G.{{cite web|url=https://numbertext.org/linux/ |title=Linux Libertine G and Linux Biolinum G for LibreOffice and OpenOffice.org desktop publishing, OpenType to Graphite conversion |publisher=Numbertext.org |access-date=2018-07-09}} Both these fonts are bundled with LibreOffice as of the suite's 3.3 release,{{cite web|url=http://www.libreoffice.org/download/3-3-new-features-and-fixes/ |title=Bundled Linux "Libertine G" and Linux "Biolinum G" fonts |publisher=Libreoffice.org |access-date=2013-09-30}} with some features added in the 3.5 release.{{cite web|title=Release Notes 3.5|work=The Document Foundation wiki|date=February 21, 2012|access-date=February 23, 2012|url=http://wiki.documentfoundation.org/ReleaseNotes/3.5#Writer}}

Khaled Hosny forked the Linux Libertine font family in 2012{{cite web |url=https://github.com/alif-type/libertinus/commit/35a578bc768b2a0fa286a1bc87c24db8e337cfb1|title=First commit of the Linux Libertine software repository|website=GitHub |access-date=20 April 2020}} that stemmed from a lack of a matching mathematical companion font for Linux Libertine. He officially released the initial version of his fork in 2016.{{Citation|title=Hosny, Khaled. The libertine gets mathematical. TUGboat, vol. 37 (2016), No. 1.|url=https://www.tug.org/TUGboat/tb37-1/tb115hosny.pdf|access-date=2017-12-17}} Due to licensing restrictions of Linux Libertine regarding the need to change the name of derivative works, he renamed his version to Libertinus fonts (including Libertinus Serif and Libertinus Sans).{{cite web |url=https://github.com/alif-type/libertinus |title=alif-type/libertinus: Libertinus Font Family |website=GitHub |access-date=27 June 2018}} Hosny also used this opportunity to unify the various font names. Thus, Linux Libertine became Libertinus Serif, Linux Biolinum became Libertinus Sans, and Linux Libertine Mono became Libertinus Mono. His new mathematical font is called Libertinus Math. While working on the mathematical companion, Hosny fixed many technical issues of the already existing fonts. This led him to a complete fork of Linux Libertine, not just adding a complementing typeface to it.{{Citation|title=Hosny, Khaled. The libertine gets mathematical. TUGboat, vol. 37 (2016), No. 1.|url=https://www.tug.org/TUGboat/tb37-1/tb115hosny.pdf|access-date=2017-12-17}} Since Linux Libertine's releases came to a halt in 2012,{{Citation|title=Sourceforge – list of releases of the Linux Libertine font|url=https://sourceforge.net/projects/linuxlibertine/files/linuxlibertine/|access-date=2017-12-08}} the actively developed Libertinus fonts are de facto a continuation of the now stalled Linux Libertine project. Khaled passed the role of maintainer on to Caleb Maclennan in 2020.{{Cite web |date=June 16, 2022 |title=GitHub – alerque/Libertinus: The Libertinus font family |url=https://github.com/alerque/libertinus#history |website=GitHub}}

Stefan Peev forked the Libertinus Serif font to create the Common Serif font in 2022.{{Cite web |accessdate=May 2, 2023 |title=GitHub – StefanPeev/Common-Serif: The Common Serif project is based on Libertinus Serif. |url=https://github.com/StefanPeev/Common-Serif#history |website=GitHub}}
