I've got the following Problem using the SIAM bibtex style. Consider the following bib entry

  author = {Author One},
  title = {Paper Title},
  institution = {My Institute},
  year = {2011},
  number = {XXX/YY-ZZ},
  month = {December},



to generate the bibliography. Then the output is

 A. ONE, Paper title, Tech. Rep. XXX/YY-ZZ, My Institute, December 2011.

How can I remove the "Tech. Rep." from the output? Setting type={} in the bibtex entry does not help and type={~} removes the "Tech. Rep. but inserts an unwanted whitespace before the number.

In this particular case


seems to work.

Thanks, the output looks like I want it. – Grisu Feb 27 '12 at 10:34
If i enter \unskip\space in the type-filed of Jabref, it does not remove the comma and the bibliography entry compiles like: ........University, , 21. September 2012. How can this be fixed, if using \bibliographystyle{unsrtdin} \bibliography{MyBibtexFile.bib} – Fry Aug 21 '14 at 16:01
@Fry This is specific for siam.bst; unsrtdin is a different beast. – egreg Aug 21 '14 at 19:25
