When I retrieve the bib data to the publication
Kloeden, Peter E. ; Kozyakin, Victor S. Uniform nonautonomous attractors under discretization. Partial differential equations and applications. Discrete Contin. Dyn. Syst. 10 (2004), no. 1-2, 423–433.
via MR Lookup, zbMath or directly from the article’s site by the link http://www.aimsciences.org/journals/displayArticles.jsp?paperID=148
I got correct bib data indicated above. I would like to mention that, for this publication, DOI=10.3934/dcds.2004.10.423
However, when in JabRef I am trying to get info for this publication using DOI (via menu BibTex -> New Entry by entering there DOI) I got the following record
Kozyakin, V. & Kloeden, P.
Uniform nonautonomous attractors under discretization
Discrete and Continuous Dynamical Systems, American Institute of Mathematical Sciences (AIMS), 2003 , 10 , 423-433
where the YEAR is DIFFERENT !!!
It seems the problem is not due to JabRef, since the same year I got by getting bibliography data using other services for which the PRIMARY data format is RIS (Crossref, Mendeley, Zotero etc.) My opinion is that the “year” record in BibTeX is not the same as the “PY” record in RIS from which the year of publication is retrieved: the “year” in BibTex means the year of “official, paper” publication of the article, while “PY” in RIS reflects “first public appearance” of the article which may be different in the case when a journal admits “first online” publications.
In any case it would be useful to make somewhere in JabRef announcement that retrieving bib data by DOI might be ambiguous.
