My bibliography (made with biblatex) has all items close to each other. I would like to introduce some space between them, e.g. half a line.

How can I do this?

increase one of the lengths:

\bibitemsep length between two different entries, preset to \itemsep

\bibnamesep length between two entries of different authors

\bibinitsep length between two entries of authors with different first letter

For example, if you want to increase the \bibitemsep by 50%, you could use:

\setlength\bibitemsep{1.5\itemsep}

    That won't work for packages where \itemsep is already zero. Better to use \setlength\bibitemsep{0.5\baselineskip} or something document-related. Jun 19, 2016 at 21:49

I've used the answer given by Herbert, but it didn't work for me. This could be probably due to the recent update of biber to v2.4 (March 2016).

Hereby, I propose an alternative that worked for me (i.e. introducing a space between the bibentries in the list):

\setlength\bibitemsep{\baselineskip}

You've to put this in the preamble right after \usepackage{biblatex}

    Mhhh, a Biber update should have nothing to do with that. A biblatex update might just, but it is extremely unlikely I would say. The more likely explanation is that your documentclass sets \itemsep to a small value so that you can't tell 1.5\itemsep from \itemsep. Without an example it is of course hard to say ...

I've used the answer given by Herbert, but it didn't work for me too. It was because {1.5\itemsep} is the default size. \setlength\bibitemsep{5\itemsep} produced what I wanted to.

  • How is the different from the previous answer (except for the changes in the separation). Welcome to TEXSE. Jul 31, 2019 at 7:21
  • Yes you are right. I'm not familiar with the interface. Thanks for welcoming me. Jul 31, 2019 at 11:32
  • Indeed, I think this is more of a comment than an answer. Could you move it to the comment? In case, if you cannot do so (due to reputation), let me know, I will do it on behalf of you :) Jul 31, 2019 at 11:45
  • The default size of \bibitemsep as defined in biblatex.def is \setlength{\bibitemsep}{\itemsep}, see l. 292 of biblatex.def. Some biblatex standard styles set \bibitemep to 0pt (authortitle- and authoryear-based styles), but none sets it to 1.5\itemsep. Maybe the \itemsep in your document is zero?

A more efficient way is to use setspace package, which helps you set the separation between lines for biblatex.

Then you can use \setlength{\bibitemsep}{10pt} to set the item separation.

Here's a sample code:

\usepackage{biblatex}
\usepackage{setspace}

\linespread{2.0}
\setlength{\bibitemsep}{10pt}

\begin{spacing}{1.0}
\printbibliography[title={Works Cited}]
\end{spacing}

  • Well, setspace does something very different from \bibitemsep. setspace influences the separation between all lines. \bibitemsep influences the space between different entries. If a single entry has multiple lines, the two will behave differently.
