I am currently converting a bibliography for a paper (which I did not write) into bibtex and I am having trouble understanding the citations in the image below: (these are not my own, this is just an example how other authors cited the papers I am interested in)

I do not have very much experience with German-language publications, and I've been told that they have some special rules associated with them such that that nouns should always be capitalized, but I can't find a source that provides a lot of detail.

What is the meaning of the two dates in citations such as this (I've also seen some with two sets of page numbers) and how should I put it into a bibtex entry? This is what I was given:

\bibitem[Cig98]{Cig98} J. Cigler, 
Operatormethoden f\"ur $q$-Identitäten. VI. Geordnete Wurzelb\"aume und $q$
\"Osterreich. Akad. Wiss. Math.-Natur. Kl. Sitzungsber. II 206 (1997), 253
-266 (1998).

and this is what I've changed it to so far

Author = {J.~ Cigler},
Journal = {\"Osterreich. Akad. Wiss. Math.-Natur. Kl. Sitzungsber. II},
Title = {{O}peratormethoden f\"ur $q$-{I}dentit\"aten.~ {VI}.~ {G}eordnete {W}urzelb\"aume und $q$-{C}atalan-{Z}ahlen}},
Year = {1997},
Volume = {206},
Pages = {253--266}

Is this okay so far? How do I finish properly entering this citation?

  • Since yoou have access to the original tex files, i would ask the guy who gave them to you for help. Just by looking at the items, i cannot say something useful; it seems strange.

  • biblatex might be better to do the job, especially with regards to capitalization. Please note, that the space between J~ and Cigler should be removed.

  • @Johannes_B Thank you, I did not notice the space at all. I'll take a look into biblatex. I agree that it seems strange, I don't understand what purpose a second date is supposed to have.

  • Are you sure it is a date? If the number in parenthesis would be 1342 i wouldn't say its a date. Maybe it is the total amount of pages? But really, this is guesswork.

  • it says "Sitzungsber[icht]", which means report to a conference or something. A conference takes place in one year, the report is published in another. Just a guess. Not really a LaTeX question :)

I'd say that "1997" is the year, "206" is the volume number, and "1996" is the issue number. I'd keep the abbreviated journal name, as I see little point in writing the full form, which would be "{\"O}sterreichische Akademie der Wissenschaften, Mathematisch-Naturwissenschaftliche Klasse, Sitzungsbericht~II".

enter image description here

  author  = "J. Cigler",
  journal = "{\"O}ster\-reich.\ Akad.\ Wiss.\ Math.-Natur.\ Kl.\ Sitzungsber.~II",
  title   = "{Operatormethoden f{\"u}r $q$-{I}dentit{\"a}ten. 
             IV\@.~Eine Klasse von $q$-Gould-Polynomen}",
  year    = 1997,
  volume  = 206,
  number  = 1996,
  pages   = "169-174",
  author  = "J. Cigler",
  journal = "{\"O}ster\-reich.\ Akad.\ Wiss.\ Math.-Natur.\ Kl.\ Sitzungsber.~II",
  title   = "{Operatormethoden f{\"u}r $q$-{I}dentit{\"a}ten.
            V\@.~$q$-Catalan B{\"a}ume}",
  year    = 1997,
  volume  = 206,
  number  = 1996,
  pages   = "175-182",

  • I think the volume number is 206 and that's about it if this link is a demonstration of that series.

  • @percusse -- That's what I'm guessing too: volume = 206.
