BUT .... I would like to argue that this not the proper way to handle a link in the Bibliography, if you would allow me. Let me list a few of the things that are wrong or are not close to the best practice.</div><div><br></div><div>1- Displaing a string like:</div><div><br></div><div> <font face="monospace"><a href="http://kconrad.math.uconn.edu/blurbs/gradnumthy/infseriespadic.pdf">kconrad.math.uconn.edu/blurbs/gradnumthy/infseriespadic.pdf</a></font></div><div><br></div><div>is incomplete and is missing the "scheme" which is this case is: <font face="monospace">https://</font></div><div><font face="monospace"><br></font></div><div>2- One should not show an URL in a text -- it has no use, no purpose -- no one should be made to type:</div><div><br></div><div> <font face="monospace"><a href="http://kconrad.math.uconn.edu/blurbs/gradnumthy/infseriespadic.pdf">http://kconrad.math.uconn.edu/blurbs/gradnumthy/infseriespadic.pdf</a></font></div><div><br></div><div>on a browser and if you want just to click you can click on a small piece of text that describe the resource, like for example:</div><div><br></div><div> ... the article "Infinite series on $p$-adic fields"...</div><div><br></div><div>If it is in bibliography you could place the link on top of the Title of the resource.</div><div><br></div><div>3- URL are the underpinning of the Internet, as we use it, they are used by browsers, viewers, apps, etc.... Displaying and URL in print is the same as going around and showing your underwear.</div><div><br></div><div>4- You should almost never have to edit a BBL file. The proper way to enter a link in a bibliography is by entering it on the BIB file as in:</div><div><br></div></div></div></div><blockquote style="margin:0px 0px 0px 40px;border:none;padding:0px"><div><div><div><div><div><font face="monospace">@article {key,</font></div></div></div></div></div><div><div><div><div><div><font face="monospace"> AUTHOR = {Camacho, César},</font></div></div></div></div></div><div><div><div><div><div><font face="monospace"> TITLE = {Structural stability theorems for integrable differential forms on {$3$}-manifolds},</font></div></div></div></div></div><div><div><div><div><div><font face="monospace"> JOURNAL = {Topology},</font></div></div></div></div></div><div><div><div><div><div><font face="monospace"> FJOURNAL = {Topology.

This does what it's supposed to do in a foo.tex file, but if I
include the exact same command in foo.bbl, like this:<p></p>

No text is printed and no hyperlink is set. Is there a way to
create hyperlinks in the bibliography?<p></p>
