This is the iso690 bibliographic style used by \OpTeX/.

See `op-example.bib` for an example of the `.bib` input. You can try it by:

\begtt
\fontfam[LMfonts]
\nocite[*]
\usebib/s (iso690) op-example
\end
\endtt

\secc Common rules in .bib files

There are entries of type `@FOO{...}` in the `.bib` file. Each entry consists of
fields in the form `name = "value"`, or `name = {value}`. No matter which form is
used. If the value is pure numeric then you can say simply `name = value`.
Warning: the comma after each field value is mandatory! If it is missing then the
next field is ignored or bad interpreted.

The entry names and field names are case insensitive. If there exist a data
field no mentioned here then it is simply ignored. You can use it to store
more information (abstract, for example).

There are \"standard fields" used in ancient bib\TeX/ (author, title, editor, edition,
etc., see \url{http://en.wikipedia.org/wiki/BibTeX}). The `iso690` style introduces
several \"non-standard" fields: ednote, numbering, isbn, issn, doi, url, 
citedate, key, bibmark. They are documented here.

Moreover, there are two optional special fields:

\begitems
* lang     = language of the entry. The hyphenation plus autogenerated phrases and
             abbreviations will be typeset by this language.
* option   = options by which you can control special printing of vairous fields.
\enditems 

There can be only one option field per each entry with (may be) more options
separated by spaces. You can declare the global option(s) in your document
applied for each entry by `\biboptions={...}`.


\secc The author field

All names in the author list have to be separated by \"` and `". Each author
can be written by various formats (the `von` part is typically missing):

\begtt
  Firstname(s) von Lastname
  or
  von Lastname, Firstname(s)
  or
  von Lastname, After, Firstname(s)
\endtt

Only the Lastname part is mandatory. Examples:

\begtt
  Petr Olšák
  or
  Olšák, Petr

  Leonardo Piero da Vinci
  or
  da Vinci, Leonardo Piero
  or
  da Vinci, painter, Leonardo Piero
\endtt

The separator \"` and `" between authors will be converted to comma during
printing, but between semifinal and final author the word \"and" (or something
different depending on current language) is printed.

The first author is printed in reverse order: \"LASTNAME, Firstname(s) von,
After" and the others author are printed in normal order: \"Firstname(s)
von LASTNAME, After". This feature follows the ISO 690 norm. The Lastname
is capitalised using uppercase letters, but if the \caps font modifier is defined,
then it is used and printed `{\caps\_rm Lastname}`.

You can specify the option `aumax:<number>`. The <number> denotes the
maximum authors to be printed. The rest of authors are ignored and the
`et~al.` is appended to the list of printed authors. This text is
printed only if the `aumax` value is less than the real number of authors. 
If you have the same number of authors in the .bib file as you need to print
but you want to append `et~al.` then you can use `auetal` option.

There is an `aumin:<number>` option which denotes the definitive number of 
printed authors if the author list is not fully printed due to `aumax`.
If `aumin` is unused then `aumax` authors is printed in such case.

All authors are printed if `aumax:<number>` option isn't given. 
There is no internal limit. But you can set the global options in 
your document by setting the `\biboptions` tokens list. For example:

\begtt
   \biboptions={aumax:7 aumin:1}  
   % if there is 8 or more authors then only first author is printed.
\entdd

Examples:

\begtt
   author = "John Green and Bob Brown and Alice Black",
\endtt

output:    GREEN, John, Bob BROWN, and Alice BLACK.

\begtt
   author = "John Green and Bob Brown and Alice Black",
   option = "aumax:1",
\endtt

output:    GREEN, John~et~al.

\begtt
   author = "John Green and Bob Brown and Alice Black",
   option = "aumax:2",
\endtt

output:    GREEN, John, Bob BROWN~et~al.

\begtt
   author = "John Green and Bob Brown and Alice Black",
   option = "aumax:3",
\endtt

output:    GREEN, John, Bob BROWN, and Alice BLACK.

\begtt
   author = "John Green and Bob Brown and Alice Black",
   option = "auetal",
\endtt   

output:    GREEN, John, Bob BROWN, Alice BLACK~et~al.

If you need to add a text before or after authors list, you can use
the `auprint:{<value>}` option. The <value> will be printed instead of the
authors list. The <value> can include `\AU` macro which expands to the authors
list. Example:

\begtt
   author = "Robert Calbraith",
   option = "auprint:{\AU\space [pseudonym of J. K. Rowling]}",
\endtt

output:    CALBRAITH Robert [pseudonym of J. K. Rowling].

You can use the `autrim:<number>` option. All Firstnames of all authors
are trimmed (i. e. reduced to initials) iff the number of authors in the 
author field is greater than or equal to <number>. There is an exception:
`autrim:0` means that no Firstnames are trimmed. This is default behavior.
Another example: `autrim:1` means that all Firstnames are trimmed.

\begtt
   author = "John Green and Bob Brown and Alice Black",
   option = "auetal autrim:1",
\endtt

output:    GREEN, J., B. BROWN, A. BLACK~et~al.

If you need to write a team name or institution instead authors, replace all
spaces by \<space> in this name. Such text is interpreted as Lastname. You
can add the secondary name (interpreted as Firstname) after comma. Example:

\begtt
   author = "Czech\ Technical\ University\ in\ Prague, Faculty\ of\ Electrical\ Engeneering",
\endtt

output:  CZECH TECHNICAL UNIVERSITY IN PRAGUE, Faculty of Electrical Engeneering.


\secc The editor field

The editor field is used for list of the authors of the collection. The
analogous rules as in author field are used here. It means that the
authors are separated by \"` and `", the Firstnames, Lastnames etc. are
interpreted and you can use the options `edmax:<number>`, `edmin:<number>`, 
`edetal`, `edtrim:<number>` and `edprint:{<value>}` (with `\ED` macro).
Example:

\begtt
   editor = "Jan Tomek and Petr Karas",
   option = "edprint:{\ED, editors.} edtrim:1",
\endtt

Output:   J. TOMEK and P. KARAS, editors.

If `edprint` option is not set then `{\ED, eds.}` or `{\ED, ed.}` is used
depending on the entry language and on the singular or plural of 
the editor(s).


\secc The ednote field

The ednote field is used as the secondary authors and more editional info. The
value is read as raw data without any interpretation of Lastname, Firstname
etc.

\begtt
   ednote = "Illustrations by Robert \upper{Agarwal}, edited by Tom \upper{Nowak}",
\endtt

output:   Illustrations by Robert AGARWAL, edited by Tom NOWAK.

The \upper command have to be used for Lastnames in ednote field.


\secc The title field

This is the title of the work. It will be printed (in common entry types) by
italics. The ISO 690 norm declares, that the title plus optional subtitle
are in italics and they are separated by colon. Next, the optional secondary
title have to be printed in upright font. This can be added by
`titlepost:{<value>}`. Example:

\begtt
   title = "The Simple Title of The Work",
or
   title = "Main Title: Subtitle",
or
   title  = "Main Title: Subtitle",
   option = "titlepost:{Secondary title}",
\endtt

The output of the last example:
{\it Main Title: Subtitle}. Secondary title.


\secc The edition field

This field is used only for second or more edition of cited work. Write
only the number without the word "edition". The shortcut "ed." (or something
else depending on current language) is added automatically. Examples:

\begtt
   edition = "Second",
   edition = "2nd",
   edition = "2$^{\rm nd}$",
   edition = "2.",
\endtt

Output of the last example:   2. ed.

\begtt
   edition = "2."
   lang    = "cs",
\endtt

Output:   2. vyd.

Note, that the example `edition = "Second"` may cause problems. If you are
using language "cs" then the output is bad:   Second vyd.  
But you can use `editionprint:{<value>}` option. The the <value> is printed
instead of edition field and shortcut. The edition field must be set. Example:

\begtt
   edition = "whatever",
   option  = "editionprint:{Second full revised edition}",
\endtt

Output:   Second full revised edition.

You can use `\EDN` macro in `editionprint` value. This macro is expanded 
to the edition value. Example:

\begtt
   edition = "Second",
   option  = "editionprint:{\EDN\space full revised edition}",
or
   edition = "Second full revised edition",
   option  = "editionprint:{\EDN}",
\endtt


\secc The address, publisher, year fields

This is an anachronism from ancient Bib\TeX/ (unfortunately no exclusive) that
the address field includes only the city of the publisher residence. No more
data are here. The publisher field includes the name of the publisher.

\begtt
   address = "Berlin",
   publisher = "Springer Verlag",
   year = 2012,
\endtt

Output:   Berlin: Springer Verlag, 2012.

Note, that the year needn't to be inserted into quotes because it is pure
numeric. 

The letter a, b etc. are appended to the year automatically, if two or more
subsequent entries in the bibliography list are not distinct by the first
author and year fields. If you needn't this feature, you can use the
`noautoletters` option.

You can use "yearprint:{<value>}" option. If it is set then the <value>
is used for printing year instead the real field value. The reason: year is
sort sensitive, may be you need to print something else than only sorting key.
Example:

\begtt
   year   = 2000,
   option = "yearpint:{© 2000}",
\endtt

Output:  © 2000,  sorted by:  2000.

\begtt
   year   = "2012a",
   option = "yearprint:{2012}",
\endtt

Output:  2012,   sorted by:  2012a.

The address, publisher and year are typically mandatory fields. If they are
missing then the warning occurs. But you can set `unpublished`
option. Then this warning is suppressed. There is no difference in the
printed output.


\secc The url field

Use it without `\url` macro, but with `http://` prefix. Example:

\begtt
   url = "http://petr.olsak.net/opmac.html",
\endtt

The ISO 690 norm recommends to add the text \"Available from" (or
something else if different current language is used) before URL. 
It means, that the output of previous example is:

Available from \url{http://petr.olsak.net/opmac.html}.

If the `cs` language is the current one than the output is:

Dostupné z: \url{http://petr.olsak.net/opmac.html}.

If the `urlalso` option is used, then the added text has the form
\"Available also from" or \"Dostupné také z:" (if `cs` language is
current).


\secc The citedate field

This is the citation date. The field must be in the form year/month/day. It
means, that the two slashes must be written here. The output depends on the
current language. Example:

\begtt
   citedate = "2004/05/21",
\endtt

Output when `en` is current:    [cit. 2004-05-21].
Output when `cs` is current:    [vid. 21.~5.~2004].


\secc The howpublished field

This declares the available medium for cited document if it is not in printed
form. Alternatives: online, CD, DVD, etc. Example:

\begtt
   howpublished = "online",
\endtt

Output:   [online].
 

\secc The volume, number, pages and numbering fields

The volume is the \"big mark" of the journal issue and the number is the
\"small mark" of the journal issue and pages includes the page range of 
the cited article in the journal. The volume is prefixed by Vol.~,
the number by No.~ and the pages by pp.~. But these prefixes depends on the
language of the entry.

Example:

\begtt
   volume = 31,
   number = 3,
   pages  = "37--42",
\endtt

Output:   Vol.~31, No.~3, pp.~37--42.

\begtt
   volume = 31,
   number = 3, 
   pages  = "37--42",
   lang   = "cs",
\endtt

Output:   ročník~31, č.~3, s.~37--42.

If you disagree with the default prefixes, you can use the numbering field.
When it is set then it is used instead of volume, number, pages fields 
and instead of any mentioned prefixes. The numbering can include macros
`\VOL`, `\NO`, `\PP`, which are expanded to the respective values of fields. Example:

\begtt
   volume    = 31,
   number    = 3,
   pages     = "37--42"
   numbering = "Issue~\VOL/\NO, pages~\PP",
\endtt

Output:   Issue~31/3, pages~37--42

Note: The volume, numbers and pages fields are printed without numbering
filed only in the `@ARTICLE` entry. It means, that if you need to visible them
in the `@INBOOK`, `@INPROCEEDINGS` etc. entries, then you must to use numbering field.


\secc Common notes about entries

The order of the fields in the entry is irrelevant. We use the printed order
in this manual. The exclamation mark (!) denotes the mandatory field. If
such field is missing then the warning occurs during processing.

If the `unpublished` option is set then the fields address, publisher, year,
isbn and pages are not mandatory. If the `nowarn` option is set then no
warnings about missing mandatory fields occurs.

If the field is used but not mentioned in the entry documentation below then
it is silently ignored.

\p The `@BOOK` entry

This is used for book-like entries. 

Fields: author(!), title(!), howpublished, edition, ednote, address(!), 
publisher(!), year(!), citedate, series, isbn(!), doi, url, note. 

The ednote field here means the secondary authors (illustrator, cover design
etc.).

\p The `@ARTICLE` entry

This is used for articles published in a journal. 

Fields: author(!), title(!), journal(!), howpublished, address, publisher,
month, year, [numbering or volume, number, pages(!)], citedate, issn,
doi, url, note. 

If the numbering is used then it is used instead volume, number, pages.


\p The `@INBOOK` entry

This is used for the part of a book. 

Fields: author(!), title(!), booktitle(!), howpublished, edition, ednote,
address(!), publisher(!), year(!), numbering, citedate, series, isbn or
issn, doi, url, note.

The author field is used for author(s) of the part, the editor field
includes author(s) or editor(s) of whole document. The pages field specifies
the page range of the part. The series field can include more information
about the part (chapter numbers etc.).

The `@INPROCEEDINGS` and `@CONFERENCE` entries are equivalent to `@INBOOK` entry.

\p The `@THESIS` entry

This is used for student's thesis. 

Fields: author(!), title(!), howpublished, address(!), school(!), 
month, year(!), citedate, type(!), ednote, doi, url, note. 

The type field must include the text \"Master's Thesis" or something 
similar (depending on the language of the outer document).

There are nearly equivalent entries: `@BACHELORSTHESIS`, `@MASTERSTHESIS` and
`@PHDTHESIS`. These entries set the type field to an appropriate value
automatically. The type field is optional in such case. If it is used then
it has a precedence before default setting.

\p The @MISC entry

It is intended for various usage. 

Fields: author, title, howpublished, ednote, citedate, doi, url, note. 

You can use `\AU`, `\ED`, `\EDN`, `\VOL`, `\NO`, `\PP`, `\ADDR`, `\PUBL`,
`\YEAR` macros in ednote field. These macros print authors list, editors list,
edition, volume, number, pages, address, publisher and year field values
respecitively.

The reason of this entry is to give to you the possibility to set the format of
entry by your own decision. The most of data are concentrated in ednote
field.

\p The `@BOOKLET`, `@INCOLLECION`, `@MANUAL`, `@PROCEEDINGS`, `@TECHREPORT`, `@UNPUBLISHED` entries

These entries are equivalent to `@MICS` entry because we need to save the
simplicity. They are implemented only for (almost) backward compatibility
with the ancient Bib\TeX/. But the ednote is mandatory field here, so you
cannot use these entries from the old databases without warnings and without 
some additional work with the `.bib` file.

\secc The cite-marks (bibmark) used when \code{\\nonumcitations} is set

When `\nonumcitations` is set then `\cite` prints text orientes 
bib-marks instead numbers. This style file autogenerates these marks in the
form \"Lastname of the first author, comma, space, the year" if bibmark field
isn't declared. If you need to set an exception from this common format,
then you can use bibmark field.

The OPmac trick \url{http://petr.olsak.net/opmac-tricks-e.html#bibmark}
describes how to redefine the algorithm for bibmark auto-generating when you
need the short form of the type [Au13].


\secc Sorting

If `\usebib/c` is used then entries are sorted by citation order in the text.
If `\usebib/s` is used then entries are sorted by \"Lastname, Firstname(s)" of
the first author and if more entries have this value equal, then the year is
used (from older to newer). This feature follows the recommendation of the
ISO 690 norm.

If you have the same authors and the same year, you can control the sorting
by setting years as 2013, 2013a, 2013b, etc. You can print something
different to the list using `yearprint{<value>}` option, see the section about
address, publisher and year above. The real value of year field (ie. not
yearprint value) is also used in the text oriented bib-marks when 
`\nonumcitations` is set.

If you have some problems with name sorting, you can use the hidden field
`key`, which is used for sorting instead of the \"Lastname Firstname(s)"
of authors. If the `key` field is unset then the \"Lastname Firstname(s)" 
is used for sorting normally. Example:

\begtt
   author    = "Světla Čmejrková",
   key       = "Czzmejrkova Svetla",
\endtt

This entry is now sorted between C and D. 

The norm recommends to place the autocitations to the top of the list of
references. You can do this by setting  `key = "@"`, to each entry with your
name because the `@` character is sorted before `A`.


\secc Languages

There is the language of the outer document and the languages of each entry.
The ISO 690 norm recommends that the technical notes (the prefix before URL,
the media type, the \"and" conjunction between semifinal and final author)
may be printed in the language of the outer document. The data of the entry
have to be printed in the entry language (edition ed./vyd., Vol./ročník,
No./č. etc.). Finally there are the phrases independent on the language
(for example In:). Unfortunately, the bib\TeX/ supposes that the entry data
are not fully included in value parts of the fields (see edition, volume
etc. fields) so the automaton have to add some text during processing.
But what language have to be chosen?

The current value of the `\language` register at the start of the `.bib`
processing is decided as the language of the outer document. This language
is used for technical notes regardless of the entry language. Each entry can
have the lang field with the two-letter mark of the entry language. This
language is used for ed./vyd., vol./ročník etc. and it is used for
hyphenation too. If the entry language is not set then the outer document
language is used.

If the outer document language is known before creating of the `.bib` file, you
can store some language-dependent phrases into it. On the other hand, if the
main document language is unknown, you can use the \Mtext macro to
create the text multilingual. Example:

\begtt
   howpublished = "\Mtext{blue-ray}"
\endtt

Now, you can set the variants of blue-ray into your macros:

\begtt
   \mtdef {blue-ray}  {Blue-ray disc}  {Blue-ray disk} {}
\endtt


\secc Tips for using more languages

This style prefers English, Czech and Slovak languages. However, you can add
more languages. You can see the avalable languages by expansion of \langlist
macro. And you can use the shortcuts of language names (`de` and `pl` in the
example below and you can define all phrases for your language:

\begtt
   \def\mtdefx#1#2#3{\sdef{_mt:#1:de}{#2}\sdef{_mt:#1:pl}{#3}}

                             % German              % Polish
   \mtdefx {bib.and}         { und }               { a }
   \mtdefx {bib.phdthesis}   {Ph.D. Dissertation}  {Praca doktorska}
   ...
\endtt

See more about language phrases in the \ref[languages] section.
