# Reference a web source using ACM reference style in WinShell

I am a Windows user. I use MikTex and Winshell editor to edit my latex script. I am working on ACM conference style. I want to reference a web source in the following format as in their template:

Rafal Ablamowicz and Bertfried Fauser. 2007. CLIFFORD: a Maple 11 Package for Clifford Algebra Computations, version 11. (2007). Retrieved February 28, 2008 from http://math.tntech.edu/rafal/cliff11/index.html

In WinShell, I have a .bib front-end view. I can choose the source type. I do not have a web in the list. So I use misc.

The problem is: how can I add this part: Retrieved February 28, 2008 from before the URL???

Here are some of the type of fields and no one is for: retrieved from :

When I tried to add the retrieved from it in the URL, it trims the spaces.

EDIT: I use: ACM-Reference-Format.bst

This is the tex file part:

\bibliographystyle{ACM-Reference-Format}
\bibliography{sample-bibliography}


This the .bib entry for a web page which I do not know how to add: Retrieved February 28, 2008 from part that the ACM reference style require before the URL as in their page: ACM reference format

@misc{chrome17,
title                = {Chrome},
year                 = {2017},
}

• Can you give us a little more to go on? We need to know what bibliography package you use (you tagged your question with biblatex, but as far as I know there is no official ACM style for biblatex, so you could be using ACM.bst, i.e. traditional BibTeX). It would also help greatly if you could show the resulting entry in the .bib file and not just screenshots (i.e. the plain text .bib file). The most convenient form you can give us the information we need is an MWE/MWEB – moewe Aug 7 '17 at 6:48
• The reference format is: ACM-Reference-Format.bst – user6875880 Aug 7 '17 at 8:40

With ACM-Reference-Format.bst you can add the date of access of an URL to the lastaccessed field (only for @misc entries, though).

\documentclass[format=acmlarge, review=false, screen=true]{acmart}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@misc{elk,
author       = {Anne Elk},
title        = {A Theory on Brontosauruses},
year         = {2016},
url          = {http://www.example.edu/~elk/bronto.pdf},
lastaccessed = {August 7, 2017},
}
\end{filecontents}

\begin{document}
\cite{elk}

\bibliographystyle{ACM-Reference-Format}
\bibliography{\jobname}
\end{document}
