For my document's bibliography, I use the babelbib package with the alpha.bst style and I create my bibliography like this:


Now I'd like to modifiy it a little bit: For example, I get my authors formated like this

Michael A. Harrison, Walter L. Ruzzo, and Jeffrey D. Ullman.

At first I want the and to be the German und and at second I would like to remove the , before the final and.

I've read about changing this in my alpha.bst file but I could not figure out how exactly...

  • Please help us (and also you) and add a minimal working example with bibliography (MWEB), that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass and ending with \end{document}. Related: tex.stackexchange.com/q/68484/124842 Is your question finaly solved with your answer? – Bobyandbob Aug 11 '17 at 14:04
  • No, I did'nt but editing my alpha.bst as described solved my issue. Thanks! – lukasl1991 Aug 14 '17 at 6:44

After some trouble, I could figure out a solution. Changing " and " to " und " was no problem. The comma issue was harder but could be solved by modifying the function format.names. I changed

        { numnames #2 >
            { "," * }


        { numnames #2 >
            { "" * }

which seems to be the correct solution.

EDIT: Here is a simple MWEB as requested.

\documentclass[oneside, openright, 12pt]{book}

        Title                    = {{Protection in Operating Systems}},
        Author                   = {Michael A. Harrison and Walter L. Ruzzo and Jeffrey D. Ullman},
        Journal                  = {Communications of the ACM},
        Year                     = {1976},

        Month                    = {August},
        Number                   = {8},
        Pages                    = {461--471},
        Volume                   = {19},

        Acmid                    = {360333},
        Address                  = {New York, NY, USA},
        Doi                      = {10.1145/360303.360333},
        ISSN                     = {0001-0782},
        Issue_date               = {Aug. 1976},
        Keywords                 = {turing machine, decidability, operating system, protection, protection system, security models, access control, HRU security model, safety},
        Numpages                 = {11},
        Publisher                = {ACM},
        Url                      = {http://doi.acm.org/10.1145/360303.360333}





It is important that the alpha.bst is located in the same directory like the tex file. It contains the above mentioned changes.

  • Note that you should rename the .bst file if you edited it. Ideally you would also add a comment at the end that indicates what you changed, the date of change and your name. (IANAL, but this might even be required by the license of the .bst file.) – moewe Aug 14 '17 at 7:09
