I am new with biblatex and I would like to format my citation such that: 1. The citations appear without the eng. that appears in each reference. 2. The names appear as Smith, J.S. as opposed to J S Smith

An example of my code looks like this:


this is an example \cite{perelson1996}

and I get the following:

this is an example [1]


[1] A S Perelson, A U Neumann, M Markowitz, J M Leonard, and D D Ho. “HIV-1 dynamics in vivo: virion clearance rate, infected cell life-span, and viral generation time.” eng. Science 271.5255 (1996), pp. 1582–1586. ISSN: 0036-8075 (Print); 0036-8075 (Linking).

Here is the original bibTex reference:

Abstract = {A new mathematical model was used to analyze a detailed set of human immunodeficiency virus-type 1 (HIV-1) viral load data collected from five infected individuals after the administration of a potent inhibitor of HIV-1 protease. Productively infected cells were estimated to have, on average, a life-span of 2.2 days (half-life t 1/2 = 1.6 days), and plasma virions were estimated to have a mean life-span of 0.3 days (t 1/2 = 0.24 days). The estimated average total HIV-1 production was 10.3 x 10(9) virions per day, which is substantially greater than previous minimum estimates. The results also suggest that the minimum duration of the HIV-1 life cycle in vivo is 1.2 days on average, and that the average HIV-1 generation time--defined as the time from release of a virion until it infects another cell and causes the release of a new generation of viral particles--is 2.6 days. These findings on viral dynamics provide not only a kinetic picture of HIV-1 pathogenesis, but also theoretical principles to guide the development of treatment strategies.},

    Hi and welcome to TeX.sx I've formatted your code sample for you (you can format code by selecting it and clicking on the {} icon.) Can you post the bibtex source of the bibliography entry itself (just this one entry).

  • Hi @AlanMunn, so if I go and search for the .bbl file created by biblatex, it is a very long file (I cannot post it here)...

  • Hi @AlanMunn, so if I go and search for the .bbl file created by biblatex, it is a very long file (I cannot post it here)... I use BibDesk to create my bibliography. If I use plain bibTex, then the bibtex source code will be the following: \bibitem{perelson1996} A.~S. Perelson, A.~U. Neumann, M.~Markowitz, J.~M. Leonard, and D.~D. Ho, ``{HIV-1 dynamics in vivo: virion clearance rate, infected cell life-span, and viral generation time.},'' {\em Science}, vol.~271, pp.~1582--1586, Mar 1996. PS: I don't see the icon for formatting code in a comment :( :(

  • In BibDesk select the reference and then in the edit menu choose "Copy as BibTeX record" and then edit your question and paste it (formatted as code).

The biblatex package is quite daunting, but many things are relatively easy to modify if you know where to look. One really useful resource is this question:

Most of my answer is contained in that answer, although I also have some experience writing my own biblatex styles.

The reason you are getting the eng. field is that your .bib entries have a lot of extra fields in them, and biblatex will print many of them if it recognizes them. In this case the eng is the language field. To remove this we use:


To change the order of names and initials we need to declare a NameAlias for the default sorting scheme that is used by numeric bibliography schemes.


Finally to change the use of initials with punctuation, we add a package option:


So the final code is (I also removed unnecessary packages from the example.)


this is an example \cite{perelson1996}

  • Thank you very much @AlanMunn ! this worked perfectly :)
