There will be a special issue of Discrete Mathematics devoted to papers presented at the conference, guest edited by Keith Edwards, Terry Griggs, Jan van den Heuvel, Stephanie Perkins, Bridget Webb and Vadim Zverovich.

Papers for publication in this special issue may be submitted either electronically before the conference, or on paper at the conference itself. Details of submission arrangements are given below, and are also available as a pdf document.

When preparing papers, please note the following points:

• Only papers presented at the conference will be considered, one paper per talk. Papers should not have been submitted elsewhere.
• Each paper must contain an abstract and a list of keywords.
• The affiliations of all the authors should be included at the head of the paper.
• The full postal address of the corresponding author should be enclosed.
• Each author should be listed with all the initials that they usually use. (Thus D.R.Woodall might appear as Douglas R.Woodall, but not as Douglas Woodall. "For bibliographic purposes, people who throw away initials are a menace!")
• The list of references should use standard Math. Reviews abbreviations for names of journals. Do not include references that are not cited in the paper.
• Use `` or `, not '', for open-quotes. (In LaTeX, `` is two ` characters.)
• Conventionally, in Mathematics only single-letter names of variables are printed in italic. Thus the crossing number of G might be cr(G), while cr(G) is c times its rank; and the transpose of A might be A^t, while A^t is its tth power.

Note that Discrete Mathematics does not publish conference proceedings as such, but only collections of journal-quality papers that happen to have been presented at conferences. We are required by the Editor-in-Chief of Discrete Mathematics to have each paper refereed by two referees to the normal standards expected in that journal. We hope that everyone who submits a paper will be willing, if asked, to act as a referee.

We aim to send the accepted papers to the Editorial Office of Discrete Mathematics in June 2008, in the hope that the volume will appear before April 2009.

Almost inevitably, the processing of a small number of papers will be held up by delays on the part of the authors, editors or, most probably, referees. When this happens, for whatever reason, these delayed papers will not appear in the special issue, but they will continue to be processed and, if subsequently accepted, will appear in a regular issue of Discrete Mathematics. Authors are presumed to be aware of the possibility of this happening, and to agree to it, when they submit their papers.

Electronic Submission

We prefer that you submit your paper electronically:

• Papers submitted electronically should be sent to bccpapers@computing.dundee.ac.uk no later than 1700 BST (1600 UTC) on Thursday 5 July 2007.
• Please do not use the Discrete Mathematics Author Gateway to submit papers to this special issue. (Authors of papers which are accepted will be asked to upload their papers to the Author Gateway at a later date.)
• Each paper should be submitted in a single self-contained file. The preferred format is pdf. Submissions can also be made in a single PostScript, LaTeX, TeX, or MS Word file.

• Please set the subject of your email to:
  Paper for BCC21: <surname of corresponding author>
• Please name the file with the name of the corresponding author, followed by the appropriate file extension, eg. euler.pdf, gauss.doc etc.
• Please send the file as an attachment. The main body of the email should contain the contact details of the corresponding author, and the name of the file containing the paper.
• Enquiries about the submission process should be directed to bccpapers@computing.dundee.ac.uk

Paper Submission

Submissions may also be made at the conference itself by submitting three paper copies to the local organizers not later than 5p.m. on Tuesday 10 July 2007. (In this case, it would be useful if you could also send an electronic version to the above email address before the end of the conference, but this is not essential.)
