Changelogs for econ.bst
==============================

## Ver. 2.5

* Changed the license of `econ.bst` to the LaTeX Project Public License.


## Ver. 2.4

* Added the function to implement certificated random author ordering propsed by
  the following article.

  Ray, Debraj ⓡ Arthur Robson (2018) "Certiﬁed Random: A New Order for
  Coauthorship," American Economic Review, Vol. 108, No. 2, pp. 489–520, URL:
  http://www.aeaweb.org/articles?id=10.1257/aer.20161492, DOI:
  http://dx.doi.org/10.1257/aer.20161492.
  
  For this, the following functions are added: `bst.use.nameorder`,
  `bst.and.nameorder`, `bst.cite.and.nameorder`, `bst.and.others.nameorder`.
  
  For the details, see the section "Certified random order" in econ-example.pdf.
  
* Changed the default value of `bst.doi.pre`.
    

## Ver. 2.3

* Changed the default setting of `bst.hide.number`.

* Modified the style for Ph.D. thesis (the title of Ph.D. thesis is treated as
  book title).
  
* Modified the style for editors to be similar to the style for authors. Now,
  the setting of `bst.author.name` is applied to editors.


## Ver. 2.2 (2017-08-19)

* Slightly changed the definition of `format.url`, `bst.url.pre` and
  `bst.url.post`.

* Changed `\it` command to `\textit` command.

* Added the function `bst.url.doi` which determines the way for displaying URL
  and DOI fields when both fields exist. You can choose three values for
  `bst.url.doi`.
  
  + `#0` -> Both fields are displayed
  + `#1` -> Only URL field is displayed
  + `#2` -> Only DOI field is displayed


## Ver. 2.1 (2013-07-09)

* URL field: In the new econ.bst, URL field can be displayed. If you set
  non-zero to `bst.show.url`, url field is displayed before note field (this is
  the default behavior). If you set zero to `bst.show.url`, url field is
  suppressed.

* Added the new function `bst.url.pre` and `bst.url.post`. These functions
  specify the strings before and after url field.

* access field: Added the new function `bst.access.pre` and
  `bst.access.post`. These functions specify the strings before and after access
  field. Note that access field is specific to econ.bst and not inherent in the
  standard bib file. The value of access field is used for accessed date for
  URL. For example, suppose that there are the following two settings in the bib
  file

        url          = {http://shirotakeda.org/en/tex/econ-bst.html},
        access       = {4th July, 2013}

  In the default econ.bst, these settings generate the reference like

        URL: http://shirotakeda.org/en/tex/econ-bst.html, accessed on 4th July, 2013.
  
* Added the new function `bst.show.doi`. If you set non-zero to `bst.show.doi`,
  DOI field is displayed before note field. If you set zero to `bst.show.doi`,
  DOI field is suppressed (this is the default behavior). Note that DOI field is
  not inherent in the standard bib file. See econ-sample.pdf for an example.

* Added the new function `bst.doi.pre` and `bst.doi.post`. These functions
  specify the strings before and after DOI field.

* Added the new function `bst.post.note`. This function specifies the strings
  after note field.

* Added new type "online". This is the document type for web page. Note that
  this is not inherent in the standard bib file and it does not work for other
  bst files.


## Ver. 2.0.1 (2011-12-05)

* Fixed bugs for sorting entries. In version 2.0, entries of book and
  incollection type are not sometimes sorted in alphabetical order.

* The previous econ.bst always puts `period' before the content of note
  field. The new econ.bst uses `comma' by default (but this depends on user
  customization).

* Added new function `bst.hide.title`. If you set non-zero to bst.hide.title,
  title is not displayed. 


## Ver. 2.0 (2011-11-10)

* Added \bysame abbreviation of alternative style.

  Suppose that there are the following three entries:

  Mazda, A., Subaru, B., and Honda, C., (2011) "ABC"
  Mazda, A., Subaru, B., and Honda, C., (2011) "DEF"
  Mazda, A., Subaru, B., and Toyota, D., (2011) "GHI"

  When you set non-zero to `bst.use.bysame` in the previous econ.bst,
  these entries are listed like

  [List 1]
  Mazda, A., Subaru, B., and Honda, C., (2011) "ABC"
  ----, (2011) "DEF"
  Mazda, A., Subaru, B., and Toyota, D., (2011) "GHI"

  That is, the abbreviation of authors by \bysame is only applied to entries
  with exactly the same name.

  In the new econ.bst, you can choose an alternative abbreviation style like

  [List 2]
  Mazda, A., Subaru, B., Honda, C., (2011) "ABC"
  ----, ----, and ----, (2011) "DEF"
  ----, ----, and Toyota, D., (2011) "GHI"

  In the new econ.bst, you can choose three values for `bst.use.bysame`.

  + `#0`: Not use bysame command.
  + `#1`: Use bysame command like List 1 (this is the default value).
  + `#2`: Use bysame command like List 2.

  For the details, see econ-sample.pdf.


* Abolished `bst.year.backward` and added `bst.year.position`.
  Now you can choose the position of year.

  If set to #0, year is always placed right after "author".

  If non-zero, year is placed at the end (before note field) except for aritcle
  type entry.

  In article type entry, the position of year changes according to the following
  rule:
  
  + `#1` -> year is placed at the end.
  + `#2` -> year is placed after journal name in aritcle type entry.
  + `#3` -> year is placed after volume in aritcle type entry.

* Added `bst.year.na.pre` and `bst.year.na.post`.  These functions are
  `bst.year.pre` and `bst.year.post` for non-article type entry. In the new
  econ.bst, `bst.year.pre` and `bst.year.post` are only applied to aritcle type
  entry.

* Added `bst.editor.btitle.order`.

  This determines the order of editor and booktitle in incollection and
  inproceedings entry.

  If `#0`,	editors - booktitle order (the default value).
  If non-zero,	booktitle - editors order.

* Added `bst.address.position`.

  You can choose the order of address and publisher by this function.

  If `#0`,	address -> publisher order (the default value).
  If non-zero,	publisher -> address order.

  
## Ver. 1.3.2 (2011-04-05)

* Fixed a bug in `bst.hide.number`.


## Ver. 1.3.1 (2010-12-17)

* Added the new function `bst.hide.number`.  If you want to hide number filed,
  set non-zero to this function.


## Ver. 1.3 (2010-12-04)

* Fixed a bug in period-comma handling.

* Changed the rule for sorting entries.

  In the previous rule, econ.bst use full author name for primary sorting
  key. For example, suppose that there are references like

  Hatoyama, Fukuda, Abe (2009) "apple"
  Hatoyama, Aso, Fukuda, Abe (2007) "orange."
  Hatoyama, Abe, Fukuda, Koizumi (2009) "grape."

  In this case, econ.bst sorts references in the following order.

  Hatoyama, Abe, Fukuda, Koizumi (2009) "grape."
  Hatoyama, Aso, Fukuda, Abe (2007) "orange."
  Hatoyama, Fukuda, Abe (2009) "apple."

  In the new rule, econ.bst uses the abbreviated author name instead of the full
  author name. That is, the econ.bst uses 

  Hatoyama et al. (2009) "apple."
  Hatoyama et al. (2007) "orange."
  Hatoyama et al. (2009) "grape."

  for the sorting key. So three articles are sorted in the following order.

  Hatoyama, Aso, Fukuda, Abe (2007) "orange."
  Hatoyama, Fukuda, Abe (2009) "apple."
  Hatoyama, Abe, Fukuda, Koizumi (2009) "grape."

* Changed the rule for attaching alphabetical index to year.

  In the previous rule, econ.bst does not attach alphabetical index to year in
  the following two articles.

  Hatoyama, Abe, Fukuda, Koizumi (2009) "grape."
  Hatoyama, Fukuda, Abe (2009) "apple."

  This means that two articles have the exactly same abbreated citation form
  "Hatoyama et al.(2009)".

  In the new rule, econ.bst attaches alphabetical index to the above two
  articles like

  Hatoyama, Fukuda, Abe (2009a) "apple."
  Hatoyama, Abe, Fukuda, Koizumi (2009b) "grape."

  So the abbreated citation form for two articles are distinguished like
  Hatoyama et al.(2009a) and  Hatoyama et al.(2009b). 


## Ver. 1.2 (2008-12-22)

* When there are successive periods and commas (for example, ".,", "..", ",,"
  etc.), the second one is removed.  In the previous econ.bst, it is difficult
  to use period and comma as delimiters at the same time because it often causes
  problems such as successive commas and periods.  The new econ.bst removes the
  second period or comma if there are successive periods and commas.

* Added new function `bst.and.others.num`.  Author names in the citation part
  are abbreviated by et al. if the number of authors is greater or equal to
  bst.and.others.num.  


## Ver. 1.1 (2008-11-17)

* Added new functions: `bst.sort.year`, `bst.and.others`, `bst.cite.and` and
  `bst.cite.ands`.

* Corrected typos.

  
## Ver. 1.0 (2007-11-20)

* The initial release.
