Editing Romanization of Ukrainian (section)

====Scientific transliteration====
''[[Scientific transliteration of Cyrillic|Scientific transliteration]]'', also called the ''academic'', ''linguistic'', ''international'', or ''scholarly'' system, is most often seen in linguistic publications on Slavic languages. It is purely phonemic, meaning each character represents one meaningful unit of sound, and is based on the [[Croatian Latin alphabet]].<ref>[http://intranet.library.arizona.edu/users/brewerm/sil/lib/transhist.html Transliteration Timeline] {{Webarchive|url=https://web.archive.org/web/20071213065157/http://intranet.library.arizona.edu/users/brewerm/sil/lib/transhist.html |date=2007-12-13 }} on the website of the University of Arizona Library</ref> Different variations are appropriate to represent the phonology of historical Old Ukrainian (mid 11th–14th centuries) and Middle Ukrainian (15th–18th centuries).<ref>{{cite Q |Q104552122 |pages=21, 40}}</ref>

A variation was codified in the 1898 Prussian Instructions for libraries, or ''Preußische Instruktionen'' (PI), and widely used in bibliographic cataloguing in Central Europe and Scandinavia. With further modifications it was published by the International Organization for Standardization as recommendation [[ISO/R 9]] in 1954, revised in 1968, and again as an international standard in 1986 and 1995.

Representing all of the necessary diacritics on computers requires [[Unicode]], [[Latin-2]], [[Latin-4]], or [[Latin-7]] encoding. Other Slavic based romanizations occasionally seen are those based on the [[Slovak alphabet]] or the [[Polish alphabet]], which include symbols for palatalized consonants.
