The CONSER Publication Pattern Project is just beginning to collect this
information in the MARC21 Holdings Format.  At present, the project is
collecting current patterns, but the intent is to keep the data up to
date.  Therefore the database will eventually contain historical data.
There has been discussion about inputting historical data.  For
information about the project, see

> Subject:       Historic data on frequency changes
>
> I need to know the detailed publication history of a title. I
> mean, all the variations in frequency or publication pattern
> since the first issue. The problem is not for a specific title,
> but for a large quantity, since we are planning to organize a
> union catalogue of serials. The reason why the complete
> historical data is needed, regardless of the specific
> collection you are cataloguing, has to do with some very
> interesting features of the software we will use. The fact is
> that I need that information, even for those portions of the
> run which are not presently held by the libraries.
>
> It seems to me that this information should be available
> somewhere, ideally in a sufficiently trustable database. I have
> consulted 'ISSN Compact' and 'Ulrichs on Disc', but both of
> them only mention the current frequency of every title.
>
> Does anybody have a suggestion?
