List of resources for dating articles and other publications - Archilegt/Myriatrix Wiki

Myriatrix biblio module has a field for capturing precise publication dates of articles. When a new bibliographic entry is being created and the "Publication Type" selected is "Journal Article", a field "Date Published" is shown in the tab "Publication". That field allows entering a date in the format "MM/YYYY" and "DD/MM/YYYY".
When dating old articles, multiple situations can occur. Sometimes the year needs correction, sometimes the specific month and day are "known" but not printed on the article's pages.

In general, for old works, we may have:

  1. A work issued in parts, each with its own date, and/or
  2. An advanced publication date, a date in which a work was printed and distributed in sufficient copies as to be considered published, and/or
  3. A bound volume or bound issue publication date, true to the date printed on the volume or issue, and/or
  4. A bound volume or bound issue publication date, different from the date printed on the volume or issue.

There are several resources for dating articles, books and other publications. The aim of this wiki is to keep a running list of those resources. It will be of help to Myriatrix users wishing to populate the field "Date Published" with correct and precise information. General guidance on dating works can be found in the International Code of Zoological Nomenclature (ICZN, 1999). Article 3 rules over the publication date of two works, Linnaeus's Systema Naturae, 10th Edition and Clerck's Aranei Svecici, which is arbitrarily set to 1 January 1758. Article 21 rules over and offers Recommendations on determination of date and range of dates. Article 22 rules over and offers Recommendations on citation of date.

Dating recent articles by choosing between their electronic early view, their electronic final version, or the date of the printed version can also be a challenge.

For new works, but especially for works that contain no new names or nomenclatural acts, we may have:

  1. An online "early view" publication date, and/or
  2. An online bound volume or bound issue publication date, and/or
  3. A printed publication date, true to the date printed on the volume or issue, and/or
  4. A printed publication date, different from the date printed on the volume or issue.

The e-dating challenge became routine for nomenclatural works after the International Commission on Zoological Nomenclature decided to allow electronic-only publication for nomenclatural purposes in 2012 (ICZN, 2012).

For new works containing new names or nomenclatural acts in Zoology, we may have:

  1. An online publication date, and correct ZooBank registration, and/or
  2. An online publication date, and incorrect or no ZooBank registration, and/or
  3. A printed publication date, true to the date printed on the volume or issue, and/or
  4. A printed publication date, different from the date printed on the volume or issue.

Besides the Code Amendment itself, guidance on what constitutes an e-publication for nomenclatural purposes can be found in Krell (2013) and in Cranston et al. (2015).

Annalen des Naturhistorischen Museums in Wien: Bauernfeind & Kourgli (2013) showed that the Annalen "were at least sometimes issued as dated preprints and that the evidence available to establish the correct date of publication must be examined carefully. Examples are provided from the 1930s. No full study of the problem is known." See: Bauernfeind, E. & A. Kourgli (2013): Dating of papers published in the "Annalen des Naturhistorischen Museums in Wien", Austria, vols. 33/1919 – vol. 83/1979.

Berliner entomologische Zeitschrift
Dates for each issue within a volume are given on the title page of the volume. See dates for issues in volume 38 at BHL. The date appearing on top of the first page of an article is not the publication date but the year to which each volume corresponds. Volume 38, issue 3 will have “1893” on the articles (e.g., page 267) but it was published in January 1894.

Biologia Centrali-Americana: Publication dates (month, year) for BCA parts (including pagination and plates) can be found in: Lyal, C. H. C. (2011): The dating of the Biologia Centrali-Americana.

For remarks on "Volume 14. Chilopoda and Diplopoda", see Lyal (2011: 77) and for the publication dates see Lyal (2011: 79, table 14).
"Volume 14. Chilopoda and Diplopoda. Pocock, R. I., 1895-1910, pp. i + 1-217, pls. i-xv. Published in 9 Parts, as set out in Table 14. Part CCVII included the unnumbered Title page. While the whole volume was published under the title 'Chilopoda and Diplopoda', the text in Parts CXXVI-CXXVII was published under the title 'Chilopoda', and in Parts CLXXX-CCVII under the title 'Diplopoda'."

Biologia Serbica: As of 2020, articles in the online edition containing new names were not regularly registered in ZooBank. Therefore works do not become available for the purposes of Zoological Nomenclature from the online publication date of an article, but from the printed edition, which bears its own publication date. For example, a Diplopoda article (https://doi.org/10.5281/zenodo.4147289) in volume 42, number 1 bears the online date of 27 October 2020, but the printed number 42 (1) bears the date November 2020.

Bulletin de la Société Philomathique a ses Correspondans: Handwritten in eighteen copies up to number 15 (September 1792); printed from numbers 16/17 (October/November 1792). An abridged edition was printed in 1802 (119 p. + pl.); it constitutes the first part of t. I of the "Bulletin des sciences, par la Société philomathique de Paris" (see https://catalogue.bnf.fr/ark:/12148/cb32724815g). The handwritten copies do not constitute published work for the purposes of zoological nomenclature, as they are excluded by Article 8.4 of the Code. To be published, a work produced before 1986 must have been produced on paper, by a printing method then conventional (such as letterpress, offset printing) or by hectographing or mimeographing (ICZN, 1999).

Bulletin du Muséum National d'Histoire Naturelle, Paris, 4e série, section A - Zoologie, biologie et écologie animales: Each number has a final page stating the date when the printing of the number was concluded and the date when the previous number was distributed (published). See example of printing date for volume 3, number 3, on page 935 of the same, at BHL. See example of distribution date for volume 3, number 3, on page 1228 of volume 3, number 4, at BHL.

Cretaceous Research: Uncertainty over when papers in Cretaceous Research were published were discussed by Ross (2021: 58): "The Editor-in-Chief has explained that from volume 103 an article numbering system was introduced so that papers in volumes are no longer consecutively paginated (Eduardo Koutsoukos, pers. comm. 2020). The ‘available online’ date was when the in-press version of a paper was uploaded. The final version is published on-line when it is assigned a volume number and the volume is referred to as ‘In progress’. Once a volume is complete then it is printed and thus published in the traditional sense. Volumes 103–107 were completed and published in 2019 even though I referred to these papers as ‘on-line’ in Ross (2020) and volumes 105–107 have ‘2020’ at the top of the papers. Volumes 108–118 were completed in 2020, however volumes 117 and 118 have the year ‘2021’ at the top of the papers. Although some papers in Volume 119 were published on-line in 2020 the volume was not completed until January 2021..."

Journal of Proceedings of the Entomological Society of London: Exact publication dates from 7th November 1834 to 30th January 1896 were recorded by Wheeler (1912). The "Proceedings" were published together with the "Transactions", except for the "Proceedings" from 1840 to 1846 inclusive, which were published in separate sheets. Since the beginning of the year 1896 each part has borne the month and day of publication, and with very few exceptions these may be taken as correct. The three cases of more important discrepancy (Vol. for 1900, Part 3; Vol. for 1903, Part 2; Vol. for 1907, Part 5) were also clarified by Wheeler (1912: 764, Appendix C). See: Wheeler, G.

Lunds universitets årsskrift, n. f., avd. 2: The articles in the Lunds universitets årsskrift, n. f., bear two parallel numbering systems, one for the volumes of the årsskrift and one for the volumes of the “Kungl.
