The cyrillic font contains all letters found in the modern (post-revolutionary) cyrillic alphabet, as well as others found by Mathematical Reviews to be necessary for rendering bibliographic information in Russian, Ukrainian, Serbian, Georgian, and other Slavic and non-Slavic languages ordinarily published in cyrillic. Accents which normally occur in these languages, as well as in such words as names of mathematicians whose work is regularly translated into Russian or one of the other languages covered by MR, are included in the font, as are all the digits and ordinary punctuation. Several cells are still empty: the number of such cells is not sufficient to hold all the additional pre-revolutionary Russian letters, and there is not yet enough experience to indicate what else might most usefully (for MR) be included.

The ``basic'' cyrillic font is |MCYR10|. Names have been assigned to a number of variations, not all of which exist yet. (In particular, there are no plans yet to create the METAFONT descriptions of the true ``italic'' letters.)

Keying of cyrillic to be rendered with this font is in accord with the current MR transliteration scheme, e.g. <#334#> Khrushchëv (|Khrushchëv|)→<#38#>#tex2html_accent_inline7024#<#38#> Zhurnal (|Zhurnal|)→<#41#>#tex2html_accent_inline7026#<#41#> Ki<#42#>ï<#42#>v (|Ki<#43#>ï<#43#>v|)→<#323#>#tex2html_accent_inline7028#<#323#> <#334#> 20

|stage for proper transition to and from cyrillic. Most of the translation from keyed input to cyrillic is implemented by ligature instructions in the font itself. A few letters require a ``chain'' of ligatures: sh→<#51#>#tex2html_accent_inline7030#<#51#>, shc→<#54#>#tex2html_accent_inline7032#<#54#> (an obvious absurdity, but the roman combination never occurs legitimately), shch→<#57#>#tex2html_accent_inline7034#<#57#>. Letters rendered with accents in transliteration are trapped by macros defined in the file |CYRACC.DEF|:ĭ (|ĭ|)→<#60#>#tex2html_accent_inline7036#<#60#>, 21 ī (|ī|)→<#63#>#tex2html_accent_inline7038#<#63#>, ï (|ï|)→<#66#>#tex2html_accent_inline7040#<#66#>. Both the macro accent traps and ligatures do the right thing in ordinary roman text and in |<#67#>#tex2html_accent_inline7041#<#67#>|; however, cyrillic items in tables cannot reliably be specified in the preamble, and in individual cells || should be preceded by || to prevent premature expansion, and thus loss, of the macro instructions.

Hyphenation is not automatically suppressed, but the patterns used will be those for English in the absence of a local override. (We do not know whether any Russian patterns exist.) For short passages, as the above sample, or isolated words, good luck may prevail.

Documentation accompanying this font will include full keying instructions, the ligature specifications, and, of course, |CYRACC.DEF|. Should the transliteration scheme in local use be different from the MR scheme (for example, an earlier MR scheme rendered <#68#>#tex2html_accent_inline7042#<#68#> as šč), it should be quite easy to modify |CYRACC.DEF| to accommodate it, and, if ligature changes are absolutely necessary, they may be implemented using the TEXware programs |TFtoPL| and |PLtoTF|.
