Paige (et al.):
The Falk-Plan series of hyperbolic (varying) projection town/city plans (largest scale in centre, decreasing outwards) has been known about – and catered for in AACR2 and/or ISBD(CM) (in UK, at least!) cataloguing rules – for decadesJ ‘Scale varies’ is the usefully near-correct statement, explained/expanded in a note on scale variation tied to this projection’s ‘peculiar’ qualities somewhere . . .

Subject: Re: Falk-Verlag (Hamburg, Germany) city maps with more than one scale
Perfect example of a "scale varies" situation Heiko, thank you so much!
So, what would one do if the actual representative fraction scale statements were not given on the map? One of the four standard phrases we catalogers can supply is "Scale varies" which would fit that situation. It would be a map like this but no RFs for the range of scale are given. Thankfully, it is pretty rare!
"Scales differ" is a different story altogether -- use when one is faced with three or more main maps and the scale of each is different from the others. [when you have two main maps and each is at a different scale then you provide each in its own 255/034 field]

Subject: Falk-Verlag (Hamburg, Germany) city maps with more than one scale
Paige asked for someone to supply an example of a cataloging record for a map with more than one scale.
OCLC #7694089 (or look at the attachment)
There are 2 scale data points in the 034, ǂb and ǂc, and it is coded 034 3_
The 255 reflects what Paige described in his post.
The Falk-Verlag (Hamburg, Germany) produced city maps with changing scales throughout the 1960s and 1970s. The maps typically show the city center in a fairly detailed fashion but that changes as the viewer moves farther away from the city center into the suburbs. The hyperboloid projection used by Falk Verlag cartographers at that time is a parabolic projection.
I remember writing the name authority file for Gerhard Falk (see attachment), the brain behind the rise of Falk-Verlag.
Mark Monmonier discusses some of his patents and innovations in _Patents and Cartographic Innovations: A New Perspective for Map History_.
For those that read German:
https://de.wikipedia.org/wiki/Falk_(Verlag)
There are thousands of these maps out there, many published as Falk-Plan.

Subject: Re: 255 with two different scales?
Linda,
Scale for the inset maps should only be given in a 500 note, as it does not pertain to the main map(s). The scale for the map proper (or "main map") belongs in 255$a. The quote you provided from OCLC pertains to a very specific situation -- a main map in which scale changes (or "varies") from the center of the map out to the outer portions of the map. Most of the maps that I know of that were created in this manner were done by companies in Germany so that tourists can see the details of the center of a city (the most historical part of the city with things such as museums or cathedrals that would attract the attention of tourists looking to visit such things). Scale thus is often shown on the map in this manner:
Scale 1:10,000 - 1:25,000
I'm hoping that one or more readers here can supply you with example records for you to see. If I find some time later today I probably can dig up one or two to send your way.

Subject: 255 with two different scales?
Hello,
I am cataloging a set of maps that provides a scale for the map proper and a scale for the inset maps. The OCLC 255 page says "If this scale within a single item varies and the largest and smallest values are known, record the range." but does not give any examples of such a 255 field. If someone has entered two different scales in an OCLC record or knows of an example of such a record, could you please send me a copy of the OCLC record number so that I can look at it and see what it looks like? Thank you. Linda Zellmer
