• Welcome to TeX.SE. Please clarify your objective. Are you looking to create a citation call-out in a footnote, or an entire formatted bib entry? – Mico Mar 30 '19 at 5:18
• For your case, perhaps \footnote{\rlap{\tiny \bibentry{Akaike1973}}} is good enough – David Purton Mar 30 '19 at 5:37
• Thank you, David. Your suggestion worked. But for a long bib entry, how to handle it in two lines rather than three. I have edited and added a long reference in my post. – Hooria Mar 31 '19 at 21:45
• Hi Mico, My purpose is how to add a reference in footnote utilizing the full line instead of broken reference in two or three lines leaving lots of space in each line. – Hooria Mar 31 '19 at 21:48

From your comments, it looks like you are trying to put as much content as possible into each line of each footnote.

You can do this by setting the footnote mark and text font to \tiny and increasing the \hsize of the text in the footnote.

I also suggest using 1. rather than the superscript ¹ for a footnote mark if you are using \tiny font size since otherwise your superscript will be the same size as the rest of your footnote.

There is also another problem with references. beamer (essentially) defines \newblock as \par which inserts your unwanted line break.

Finally, there is also an unwanted strut added to beamer's \newblock, which we can remove.

• That's great. This is what I want. But it is not working for a reference in a footnote. A long reference is still broken in the midway of a line and goes to the next line. Could you please further suggest something? – Hooria Apr 1 '19 at 18:59
• @Hooria, Oh! I see what you mean. I'll update my answer. – David Purton Apr 2 '19 at 4:00
• Perfect. It is really I wanted. But when I use your suggestions in my original file, it is printing thefnmark' at the start of reference instead of 1 and default' before journal name. I request to please help a bit more in this regard. – Hooria Apr 2 '19 at 7:33
• @Hooria, oops. Try now. I forgot to fix a copy/paste error. – David Purton Apr 2 '19 at 7:52
• Hi David....Just one step far--the code is now only printing 'thefnmark' at the start of reference instead of 1. Could you please help a bit more ? – Hooria Apr 3 '19 at 0:02
