# Disabling “[Online]. Available:” from References in IEEETran.cls in Overleaf

How do I remove "[Online]. Available:" from References in IEEETran.cls in Overleaf? I am currently using \def\url#1{} to disable the URL. Thank you for your help.

• Welcome to TeX.SX! Could you please add a minimal working example with bibliography (MWEB) that allows others to reproduce the issue you describe? – leandriis Jul 15 '19 at 18:00
• Did you mean IEEEtran.bst (the bibliography style file) or IEEEtran.cls (the LaTeX document class file)? I would be very surprised if it turns out that the document class governs the insertion of strings such as [Online]. Available: in the formatted bibliographic entries. That's usually the job of the bibliography style file. Please advise. – Mico Jul 15 '19 at 19:25
• Please also clarify your actual typesetting objective? Is it to suppress the typesetting of URL strings in the bibliography? If that's not the case, what else are you trying to achieve? – Mico Jul 15 '19 at 19:27
• I was wrong to assume that it was IEEEtran.cls. It should be IEEEtran.bst. Here is an example. overleaf.com/6133299219cjwsjhyzpbnb. Only the third reference shows the issue. – Rashed Jul 16 '19 at 17:30

• This is indeed possible using BBT. You can just add the url field to fields to omit preference. – retorquere Jul 21 '19 at 23:09
