DOCBOOK: bib lists

["Dave Pawson" <dave dot pawson at virgin dot net>]

Having just marked up a shortish bib list for
the first time in docbook, a couple of questions
then a request for the more experienced to see
if its marked up reasonably.

1. Are initials such as Pawson JD marked up as firstname?
2. When a document being referenced is some periodical,
   does the title get marked up as title or citetitle?
3. whats the difference between authorgroup and a series
    of author tags (none is an easy answer :-)

E.g.

  <bibliomixed><authorgroup>
	      <author>
		<surname>Gill</surname>
		<firstname> J M</firstname></author>  <author>
	      <surname>Humphreys</surname>
	      <firstname> J  A</firstname></author>
</authorgroup><title>Feasibility Study on a Braille Transcription
Service for Short Documents. </title>
	    <citetitle>Braille Automation Newsletter,</citetitle> <pubdate>Aug
1976,</pubdate><pagenums> pp 19-24.</pagenums></bibliomixed>

Others I'm unsure of

 <bibliomixed><author>
	      <surname>Gill</surname>
	      <firstname> J M</firstname></author>  <title>The Use of
Digitally-Stored Text for Braille Production.</title>  <publisher>
	      <publishername>National Computer Conference,</publishername>
	      <address> New
		York,</address></publisher> <pubdate>June 1976.</pubdate>  Reprinted in
<title>Braille Automation Newsletter,</title> <pubdate>Aug 1976,</pubdate>
<pagenums>pp
	      6-10;</pagenums> and in <title>Sigcaph
	      Newsletter,</title> <publishername>ACM, No 20,</publishername>
<pubdate>July 1976,</pubdate> <pagenums>pp 21-24.</pagenums></bibliomixed>

Whatever ACM is, is that about right?

A publication from a conference proceedings, publisher or
???
Below I have a -republished type thing
'and in' etc. Can this be explicitly tagged,
or is it 'bent' to fit?

 <bibliomixed><author>
	      <surname>Gill</surname>
	      <firstname> J M</firstname></author>  <title>The Use of
Digitally-Stored Text for Braille Production.</title>  <publisher>
	      <publishername>National Computer Conference,</publishername>
	      <address> New
		York,</address></publisher> <pubdate>June 1976.</pubdate>  Reprinted in
<title>Braille Automation Newsletter,</title> <pubdate>Aug 1976,</pubdate>
<pagenums>pp
	      6-10;</pagenums> and in <title>Sigcaph
	      Newsletter,</title> <publishername>ACM, No 20,</publishername>
<pubdate>July 1976,</pubdate> <pagenums>pp 21-24.</pagenums></bibliomixed>

Thanks for any advice,
a docbook newbie (I hate bibs already)
