I don't think so.  I vaguely recall seeing something about this number in some of the masses of documentation I've skimmed recently.

Thanks for the link.

Thanks for the suggestion, but I think for my purposes, it would be more straightforward to parse the PICA (or MARC, or whatever) data and write it to my (tabular) database.  I have already written routines for reading XML data from OAI interfaces and writing them to the same databank.  I use the stored system procedure `sp_xml_preparedocument' in MS SQL Server 2003 to extract the information from the XML expressions.  It's a bit tricky getting the data out of the hierarchical XML format and into tables, so I wouldn't mind not doing it, if I don't have to.  XML is something else I've had to learn for this project, and my knowledge of it is still rudimentary. 

Thank you for your help.  I feel a bit more confident now, after your answer and Heikki's.

Laurence
