I am having an odd problem; sometimes the full list of authors is inserted in the text, ie. the citation is not shortened to name et al. (which is what I want). I am confident it is not an error in the bibtex entry, as it happens for the same citation, when the cite key is simply copied and pasted from the bib file. The only potential pattern I can spot as to when full author list is cited, is sometimes it does it for the first citation in a new \section environment.
I am using the natbib package with the report document class.
Any thoughts would be appreciated.
[Tex/LaTex] citation call-outs: not always “et al”, sometimes full author list

The function calc.label in apalike.bst is responsible of this: it strips away all non alphanumeric characters and keeps the last up to four characters remaining.
If you copy apalike.bst to myapalike.bst and change the function defined in lines 896-912 to become
FUNCTION {calc.label}
{ type$ "book" =
type$ "inbook" =
or
'author.editor.key.label
{ type$ "proceedings" =
'editor.key.label % apalike ignores organization
'author.key.label % for labeling and sorting
if$
}
if$
", " % these three lines are
* % for apalike, which
year field.or.null #-1 #4 substring$ % uses all four digits
*
'label :=
}
then \bibliographystyle{myapalike} will accept year={n.d.} as you wish: it consists of four characters, after all!
The change consists simply in removing the string purify$. I can't say if this may have adverse effects on other entries; but, as long as you have only years or n.d., all should go well.

The dcu bibliography style -- "dcu" stands for "Design Computing Unit",
Department of Architectural and Design Science, University of Sydney -- is part of the harvard citation management package. (Aside: If you use dcu with the natbib package instead of the harvard package, it's a good idea to load the har2nat package as well, especially if the hyperref package is in use.)
As you've discovered, the dcu bibliography style is programmed not to employ the et al abbreviation in citation call-outs if there are two (or more) multi-author entries which (a) start with the same first author and (b) do not have all authors in common. In this regard, dcu is similar to the agsm bibliography style, which -- not coincidentally! -- is also part of the harvard citation management package. See the posting AGSM bibliography style sometimes doesn't abbreviate to "et al." for duplicate author+year for more on this subject.
The upshot: If you can't stand this behavior, you should probably look into using a different bibliography style.

It looks like you're loading the
natbibpackage with the optionlongnamesfirst. This option, if set, tells natbib to generate citation call-outs that include the surnames of all authors the first time a given entry with three or more authors is cited; all subsequent citation call-outs of the same entry using the\citetand\citepmacros will be of the formfirst-surname et al.If you don't want this behavior, don't specify the option
longnamesfirst.
