This file contains a list of journal names 87 equivalences: a capital-letter acronym, the abbreviated form, and the title 88 of the journal, all three on one single line. 89 90 The <tt>abbreviations.txt</tt> file has the following structure: 91 \verbatim 92 JA|J. Abbrev.|Journal of Abbreviations 93 AN|Am. Nat.=Amer. Naturalist|American Naturalist=The American Naturalist 94 \endverbatim 95 96 The first field, the capital-letter acronym, is a user-defined shorthand to 97 access a journal title by typing it at the extraction panel. 98 99 The second field is the abbreviated form of the journal. To adapt to multiple 100 abbreviations in use, cb2Bib allows one alternate version of the 101 abbreviation, indicated with an equal sign <tt>=</tt>. In the above example, 102 the ISO 4 abbreviation 'Am. Nat.' is the primary one and 'Amer. Naturalist' 103 is the alternate one. 104 105 Finally, the third field is the full title of the journal. As for the 106 abbreviations, the full title also admits one alternate form. 107 108 Abbreviated and full title alternates serve two purposes: journal recognition 109 and citation styling. The former is performed internally by cb2Bib as part of 110 a bibliographic reference extraction, and the latter is accomplished in the 111 embedded BibTeX editor by replacing back and forth abbreviated-full forms, in 112 order to set journals in accordance to the guidelines of a particular 113 publication. 114 115   116 117 Journal names processing is performed whenever a string is recognized as 118 'journal', and, additionally, when pressing <tt>Intro Key</tt> at the journal 119 edit line. 120 121   122 123 - Retrieves Journal name in abbreviated form if found. 124 125 - If Journal name is not found in the database, returns input Journal name. 126 127 - Search is case insensitive. 128 129 - **Warning:** Journal codes can be duplicated. If duplicated, returns 130 input Journal name. 131 132   133 134 - Retrieves Journal name in full form if found. 135 136 - If Journal name is not found in the database, returns input Journal name. 137 138 - Search is case insensitive. 139 140 - **Warning:** Journal codes can be duplicated.
