Editing Helvetica (section)

===Helvetica Textbook===
Helvetica Textbook is an alternate design of the typeface, which uses 'schoolbook' [[stylistic alternates]] to increase distinguishability: a seriffed capital 'i' and 'j' to increase distinguishability, a 'q' with a flick upwards and other differences, such as the digits '1' and '4' similar to how handwritten digits are. The letters 'a', 't', 'u', and the digits '6' and '9' are replaced with designs similar to those in geometric sans-serifs such as those found in [[Futura (typeface)|Futura]], [[Akzidenz-Grotesk#Akzidenz-Grotesk Schulbuch|Akzidenz-Grotesk Schulbuch]], and Avant Garde (except for 'u').<ref>{{cite web|title=Helvetica Textbook|url=https://www.fontshop.com/families/helvetica-textbook|website=FontShop|access-date=20 March 2016|archive-date=27 March 2016|archive-url=https://web.archive.org/web/20160327211155/https://www.fontshop.com/families/helvetica-textbook|url-status=live}}</ref> [[FontShop]]'s FF Schulbuch is similar.<ref>{{cite web|last1=Coles|first1=Stephen|title=Wikipedia Redefined|url=http://fontsinuse.com/uses/2013/wikipedia-redefined|website=Fonts In Use|date=26 August 2012|access-date=13 July 2016|archive-date=20 August 2016|archive-url=https://web.archive.org/web/20160820220653/http://fontsinuse.com/uses/2013/wikipedia-redefined|url-status=live}}</ref><ref>{{cite web|last1=Coles|first1=Stephen|title=Design Museum|url=http://fontsinuse.com/uses/11997/design-museum-identity-2003-2016|website=Fonts In Use|date=20 March 2016|access-date=13 July 2016|archive-date=14 August 2019|archive-url=https://web.archive.org/web/20190814170604/https://fontsinuse.com/uses/11997/design-museum-identity-2003-2016|url-status=live}}</ref>
