   I have a question about creating two sections of \bibitems. Is there a
   *.bst that could do this (doubtful) or some other mechanism? Any
   suggestions?  I'd like to have both a References section (formed from
   the \cite commands in the text) plus a Bibliography section (formed
   from the \nocite command or some other way) at the end of my text. The
   references would be a normal \bibstyle{alpha} collection of texts used
   as references within my text. 

   Thanx

I wrote the bibunits style to something similar to what you have. The
style allows you to specify references by sections or chapters or to
define a bibunit environment with its own separate references. Also is
possible to specify if a citation in a bibunit must be included in the
general bibliografy or not.

The only problem with this style is that the message of rerun to get
cross-references right ALWAYS appears. ANY IDEA OF HOW TO CORRECT
THIS?

%% BIBUNITS.STY     by Jose Alberto Fernandez (alberto@cs.umd.edu)
%% 
%% BIBUNITS is a style to generate separate bibliographies for
%% different units (parts) of the text (currently only one of
%% chapters, sections or bibunit-environments). 
%% The style will separate the citations of each unit of text into a
%% separate file to be processed by bibtex. The global bibliography
%% section produced by LATEX also can appear in the document and
%% citations can be placed in both at the same time.
%% 
%% Use the \bibliographyunit[<unit>] (<unit> = \chapter, \section) to
%% select how the references will be generated. (For every chapter or
%% for every section). Use \bibliographyunit with no arguments to
%% deactivate bibliographyunits. By default citations will only appear
%% in the local bibliography. WARNING: By default \bibliographyunit is
%% in a deactivated state.
%% 
%% If \bibliographyunit is active the \bibliography{bibtex-files} and
%% \bibliographystyle{style} commands also specify the bibtex-files
%% and style to be used by default in the local units. The commands
%% \bibliography*{<bibtex-files>} and \bibliographystyle*{<style>}
%% specify the defaults for BIBUNITS and not generate any information
%% for the global bibliography. WARNING: This values are taken as
%% defaults only when executed after activate \bibliographyunit
%% 
%% The environment \begin{bibunit}[<style>] .. \end{bibunit} allows
%% the creation of a unit while \bibliographyunit is not active. The
%% optional parameter <style> specifies a style for the biblography
%% different from the default if any. WARNING: The use of this
%% environment while \bibliographyunit is active can produce extrange
%% results. Note that default style and bibtex-files only exist if
%% specified while \bibliographyunit was active.
%% 
%% Use \cite and \nocite to generate citations. \cite* and \nocite*
%% can be use to generate citations to be added in both the local and
%% global bibliography while inside a unit.
%%
%% You must insert the command \putbib[<bibtex-files>] before the end
%% of each <unit> in the location where you want the bibliography to
%% be inserted. If the optional argument is ommited, \putbib uses the
%% default bibtex-files if any.
%% 
%% BIBTEX processing:
%% For each <unit>, in sequence, there is now a corresponding file 
%% \jobname.\the\@bibunitauxcnt.aux that need to be compiled though
%% BIBTEX as well as the \jobname.aux that generates the global
%% database. 
%% 
%% Suppose your document is foo.tex, you must now invoke bibtex not only
%% on foo, but also on foo.1, ..., foo.n given that there are n
%% different <units> with separate bibliography.
