Ifigenia,

It is a policy decision at the local level, the cataloger (perhaps in tandem with the map librarian) needs to decide first which is the predominant resource, the book or the maps. Sometimes that is pretty straightforward, a book is about a broad topic and the maps truly serve as illustration or enhancement to visually show the geographic area(s) involved, in which case one catalogs the book and uses 300$e as you denoted to indicate the maps as accompanying material (and then if one wishes to bring out specifics about one or both maps uses 500 notes). However, if the book/booklet seems to be something like a guide or similar resource supporting the maps, or explanatory text specific for use with the maps, then catalog the maps and use a linking field to share the relationship with the maps to the specifics of the book. This is usually done using the MARC 773 Host Item Entry field, the definition of the field is pretty clear about its use in such an instance. This field also allows for specific information regarding the book that the cataloger wishes to share to be brought forth as well.
