latex bibtex escape characters problem
If the escape character \ does not work for example:
@misc{SIFTWiki,
title = "SIFT Atricle",
author = "Wikipedia",
year = "2008",
howpublished = "http://en.wikipedia.org/wiki/Scale-invariant\_feature\_transform",
}
is a correct bibtex entry, but you still could get some error messages. The solution is to delete the *.bbl temporary file and run latex/bibtex again. It worked for me. It is because you probably use the latex-bibtex-latex-latex execution flow, and the first latex can not complete, so the bibtex is not started.
