bibtex references

[Lukas Wiget]

Hi,

I've added a set of bibtex references to a .lyx document. When I try to 
make a citation, only the first entry from the bibtex database is shown 
in the "Citation" dialog box. Entries in the database look like this:

@book{Abercrombie67,
   Author = {Abercrombie, David},
   Title = {Elements of general phonetics},
   Publisher = {Edinburgh University Press},
   Address = {Edinburgh},
 Year = {1967} }
@article{Abramson77,
   Author = {Abramson, Arthur S.},
   Title = {Laryngeal timing in consonant distinctions},
   Journal = {Phon\-etica},
   Volume = {34},
   Pages = {295--303},
 Year = {1977} }
@incollection{Braun96,
   Author = {Braun, Angelika},
   Title = {Zur regionalen {Distribution} von {VOT} im {Deutschen}},
   BookTitle = {{Untersuchungen} zu {Stimme} und {Sprache} -- Papers on
speech and voice},
   Editor = {Braun, Angelika},
   Publisher = {Franz Steiner},
   Address = {Stuttgart},
   Pages = {19--32},
 Year = {1996} }
Is there anything wrong with them? Note that I have used this database 
in a .tex document without any difficulties at all.

Best wishes and thanks in advance
Lukas
