I'm using the Elsevier article template. The problem is that bibliography article entries are not displayed as expected: the year is missing. Other entries (such as thesis) are displayed fine.

I'm using:

\bibliographystyle{elsarticle-num}

One of the entries (from the .bib file) that is troubling me is:

@article{dasilva2009,
year = {2009},
author = {Lawinscky da Silva, D. M.  and de Lima., M. H. A. and Jacob, B. P.},
journal = {International journal of Modeling and Simulation for the Petroleum Industry},
month = jun,
number = {1},
title = {{Numerical Model for the Simulation of the Pipeline-Laybarge interaction in pipelaying procedures}},
volume = {3}
}

Any idea what could be the cause of this behaviour? If I switch to elsarticle-harv bibliography style, it lists all items fine.

There seems to be a bug in elsarticle-num.bst regarding the year; if I remove the year field leaving month, BibTeX raises no "there's a month but no year" warning as it should. –  egreg Mar 5 '13 at 10:33

elsarticle-num.bst is deprecated now. So you may use elsarticle-num-names.bst instead. You may download it from the following site:

or direct from elsevier: elsevier.com/author-schemas/the-elsarticle-latex-document-class (a range of bst files to download at the bottom of the page) –  craq May 22 '13 at 8:59
    
I just realised that River Valley does the latex development for Elsevier. Then maybe user30304's link is better –  craq May 22 '13 at 11:05

There's something very strange in elsarticle-num.bst: many functions for processing entries miss a format.date instruction. Since the year is fundamental information for a bibliography entry this should be regarded as a bug.

You can get around this bug by making a copy of elsarticle-num.bst and adding

format.date output

before each fin.entry in

FUNCTION {article}
FUNCTION {book}
FUNCTION {inbook}
FUNCTION {incollection}
FUNCTION {inproceedings}
FUNCTION {proceedings}

However, this is only a rough workaround, as it's difficult to guess what the intentions of the developers are.
