# Bibliography error: "Use of \blx@bbl@verbadd@i doesn't match its definition. \verb"

Currently having problems with compiling my Master's thesis after downloading the newest version of TeXStudio and MiKTeX. The error message is as follows:

Use of \blx@bbl@verbadd@i doesn't match its definition. \verb


The only other place I found a similar question regarding this error message was found here: Biblatex: include bbl, problem with "verb" field

I am not sure how this applies to my problem, but from what I understand this is due to some problem in an external file. If you need the bibliography-entry, I can provide you with that on short notice, though it is rather long (which is why I didn't include it here in the first place).

I am using Mendeley Desktop v1.16.1 to automatically generate my BibTeX database.

I am using biblatex as follows:

\usepackage[backend = bibtex,
style = numeric-comp,
sorting = none,
natbib = true,
doi = false,
isbn = true,
hyperref = true]{biblatex}


I also have some code to change how the bibliography output, but I doubt it is causing the problem, as commenting it out did not help.

Hope anyone knows what causes my problem and how to fix it.

Thanks.

This bug is now fixed in biblatex: if you are experiencing it you should update your TeX system.

Following text is retained for historical record.

This is a bug in the BibTeX support for biblatex and is already fixed in the development version. As a temporary fix, adding

\makeatletter
\def\blx@maxline{77}
\makeatother


after loading biblatex should work (after LaTeX/BibTeX/LaTeX).

The detail is that in order to update the BibTeX support to bring it into line with Biber, some additional items had to be added to the .bbl file BibTeX produces. This alters an indent, which needs to be set to correctly write verbatim material. Unfortunately I overlooked that in the earlier update.

• Thank you for the quick and easy answer! It worked brilliantly! You have no idea how relieved I am right now. May 25 '16 at 14:42
• I am having the same problem right now; unfortunately your fix doesn't work for me. Jul 13 '16 at 11:05
• @user1488118 Please open a new question showing your issue: certainly the above does work for the case reported here. Jul 13 '16 at 13:23
• the fix worked for me, after add the above section in my .tex file. thanks. Jul 15 '16 at 15:20
• Worked for me too! (I forgot to compile bibliography beforehand, but now it's fine :) ) Aug 29 '16 at 18:27

Above solution did not work for me. I am using svn41193-20120634 release on openSUSE_Leap_42.2. It is probably the latest release.

Following fixed it for me. On my bibliography file bib.bib I ran the following command.

 biber --tool -V bib.bib 

It generated a _bibertool.bib file in current working directory. I guess this tool also fixes the offending entries. I used this file in my latex file and everything compiled just fine.
