Question:
Is there a way to easily force apalike.bst to drop article titles...?
(Remark: I updated this answer in after EL_DON posted a comment to note that the original answer, posted way back in August 2011, no longer works, presumably because of some update that was applied to BibTeX in the meantime.)
Short answer: Yes.
Longer answer: I suggest you proceed as follows:
Find the file apalike.bst in your TeX distribution. Make a copy of this file and call the copy, say, apalike-notitlefield.bst. (Do not edit an original file of the TeX distribution directly.
Open apalike-notitlefield.bst in a text editor. The program you use to edit your tex files will do fine.
Find the function format.title. (In my copy of the file, this function starts on line 264.)
In this function, locate the line
{ title "t" change.case$ }
Change this line to
{ "" }
Essentially, you're now instructing BibTeX to do nothing with the title field even if it's non-empty.
Save the file apalike-notitlefield.bst either to the directory that contains the main tex file (that's the file that contains \bibliographystyle and \bibliography directives) or to a directory that's searched by BibTeX. If you choose the second option, be sure to update the filename database of your TeX distribution suitably.
In the main tex file, change
\bibliographystyle{apalike}
to
\bibliographystyle{apalike-notitlefield}
and perform a full recompile cycle -- LaTeX, BibTeX, and LaTeX twice more -- to fully propagate all changes.
A final remark: This answer is known to work with the apalike bibliography style. It should with many other bibliography styles as well, as long as they provide a function called format.title.
For completeness' sake, here's the original answer from late August 2011:
Yes! It requires only some minimal surgery. First, find the file apalike.bst on your system and open it in your favorite text editor; on my system, its first two lines are:
% BibTeX `apalike' bibliography style (version 0.99a, 8-Dec-10), adapted from
% the `alpha' style, version 0.99a; for BibTeX version 0.99a.
Then locate the construct ENTRY{...} (begins on line 43 on my copy of apalike.bst) and, in that construct, the line containing the single word
title
(line 62 in my copy). Comment out this line by placing a single % comment character at the start of the line. Save this file as, say, myapalike.bst somewhere where TeX/LaTeX can find it. If you use TeXLive, for instance, you'll additionally have to run (with sudo privileges) the command mktexlsr; if you use MikTeX, you'll have to call up the Settings program and click on "Refresh FNDB".
Incidentally, this technique -- of commenting out a line in the ENTRY construct of a bst file in order to avoid it showing up in the bibliography printout -- is perfectly general. For instance, if you want to have a style file that never prints out the name of the journal in which some article is published, you could comment out the line journal and obtain the desired result.
Finally, do note that if you run LaTeX on the file makebst.tex to create your own bst file from scratch, you will still have to hand-edit the resulting bst file, as the program does not give you a choice to omit the title of a journal article entirely. Instead, it asks if you want to place the title in quotation marks and how the quotation marks are supposed to look like, e.g., single or double quotes, or single or double guillemets.
