I'm writing my first document in LaTeX and I'm using natbib for the bibliography and dcu as the style.

This is what I've written:

@miscet,
author = "Engineering Toolbox",
year = "2003",
title = "Young's Modulus - Tensile and Yield Strength for common Materials",
URL = "urlhttps://www.engineeringtoolbox.com/young-modulus-d_417.html",
note = "[online]"

This is what I get when I try to compile it.

I've used the url package with usepackageurl in the .tex file, and putting the URL in url in the .bib file. It doesn't work with or without url and I don't know what to do.

Also I've put [online] in note because the actual style I'm trying to replicate requires it but I don't know if it will appear correctly as I haven't seen the file compile yet. The [online] is supposed to come after the title.

Some suggestions and comments:

• Since you're using the dcu bibliography style, which is part of the harvard citation management package, you should load the har2nat package to optimize interoperability with the natbib package. Doing so is especially important if you plan on using the hyperref package as well.




• The dcu bib style recognizes a field called url. Hence, no need to encase the URL string in a url.. "wrapper".



• 
  

  If you don't like the default behavior of harvardurl, just follow @moewe's advice and issue the directive

  
  
  

  renewcommandharvardurl[1]url#1 % per @moewe's suggestion
  

  
  



• Since the author of the piece is a "corporate" entity, be sure to encase its contents in an extra pair of curly braces. This will prevent BibTeX from parsing the name as having first-name component "Electrical" and surname component "Toolbox".
