  • B - Bulletin
    Bulletin Bulletins address issues of state-wide or regional importance, often in a comprehensive treatment.
     

  • BGA - Bouguer Gravity Atlas of California

  • RGM - Regional Geologic and Geophysical Map
    1:250,000-scale geologic maps with individually tailored legends. Typically these maps are more detailed than GAM products. Map colors of common units typically do not vary from sheet to sheet, but identical colors may be used for different formations on different sheets.


2.     The application currently allows a user to search by a particular year, county or type of publication.  We are not allowing a user, for example, to enter a county and year and gets results for both criteria.  As we introduce new functionality to the search application we will allow the user to search based on more than one criteria.  We will have this option available as we add improvements.

3.     The following is a list of the fields that are displayed when a search is performed.
 

PUB ID  =  Publication ID Number
Title   =  Title of Publication
Year  =  Year of Publication
Price  =  Price for ordering the Publication (does not include shipping and handling charges).  An "F" or "R" may follow a price for a publication.  This indicates that a flat ("F") or rolled ("R") map version is included with the publication.
Author  =  Author(s) involved in writing Publication
Type  =  Type of Publication
County  =  County the Publication covers
