New to Latex, I just encounter a very strange problem that I cannot use \BibTeX in reference file, when I add \BibTeX to my bib file in the tile filed and reference it in the document, it raises the error of undefined control sequence, but I saw in other pdf, it was used and correctly generated. Can anyone help? Thanks very much! The bib entry is like this:

  author        = "Ki-Joo Kim",
  title         = "A {{\BibTeX}} Guide via Examples",
  howpublished  = "{bibtex\_guide.pdf}",
  url           = "http://www.geocities.com/kijoo2000/",
  month         = apr,
  year          = "2004"

the error from the bbl file is like :

K.-J. Kim. (2004, Apr.) A {{\BibTeX}} guide via examples. {bibtex\_guide.pdf}.
  [Online]. Available: \url{http://www.geocities.com/kijoo2000/}

    Welcome! That's not an error. That's a bibliography entry. The .bbl is your bibliography. The log will contain the error. But \BibTex is never usually defined, unlike \BibTeX. So if your error is the one you report, you probably just misspelt the macro. (Or mis-punctuated it or whatever you call it when you fail to copy weirdly-capitalised thingies accurately.) – cfr Sep 7 '17 at 1:20

    But \BibTeX is also not a core command. Did you load a package or class which defines it? Or did you define it? – cfr Sep 7 '17 at 1:21

    Write Bib\TeX instead of \BibTeX. – Henri Menke Sep 7 '17 at 2:09
  • \newcommand{\BibTeX}{B\kern-0.08em\textsc{i\kern-0.017emb}\kern-0.15em\TeX} should work... – Mico Sep 7 '17 at 5:20
