I have search all around but cannot seem to find the solution for getting a capital angstrom symbol (an "A" with a small circle above it) to appear in the bibliography of my dissertation. Instead, it appears as lower case "a" with circle above it.

The \AA command works just fine to generate the capital Angstrom symbol in the actual flow of my dissertation, but for some reason it doesn't work when used in the .bib file. Can someone point me to the corresponding command to get the capital Angstrom symbol to display properly in the .bib file?

Have you tried wrapping an extra pair of braces around it? I.e., {\AA}. – Harald Hanche-Olsen Jan 14 '11 at 15:26
Yes, unfortunately that isn't working - for both \AA and {\AA}, I get the lower-case angstrom symbol ("a" with circle on top). – ralphey Jan 14 '11 at 15:33

title={The unit {{\AA}ngström}},

should work

Well, if you get to use the letter ö, I don't see why not Å as well? – Harald Hanche-Olsen Jan 14 '11 at 15:55
if it is in the title entry, then it will be converted to lowercase (except the very first letter) and the double {{..}} prevent it from converting – Herbert Jan 14 '11 at 15:58
Thanks Herbert - that did the trick! – ralphey Jan 14 '11 at 16:12

You can just put in your .bib file as:

{{\AA}}, it will display angstrom symbol in capital A.

What's the diffrence between your answer and the one from Herbert? – Romain Picot May 10 at 6:25
For displaying angstrom in capital A, it is {{\AA}} not {{\AA}ngstrom}, thats a difference Dear Mr. Picot. – Gobind Ji Rai_Delhi University May 10 at 12:01
{{\AA}ngstrom} have an angstrom in capital A as far as I know. So the answer is still the same as the one provided by Herbert ;-) – Romain Picot May 10 at 12:35
{{\AA}ngstrom} will display word Angstrom , not display symbol Å, so for displaying only symbol Å, you have to put {{\AA}} not {{\AA}ngstrom}. From beginning, this I want to say. Even after that you have any doubt , you can freely to ask me, Thanks. – Gobind Ji Rai_Delhi University May 11 at 3:38
