Search Parameters: A Primer.

But first a few rules of thumb. 

Rule of Thumb #1:  Correct syntax is critically important.
Rule of Thumb #2:  The search engine is not case-sensitive.
Rule of Thumb #3:  Do not use quotation marks.
Rule of Thumb #4:  “All of the conditions required” is an exclusive search; “Any of the conditions required” is an inclusive search.   Choose wisely!

Refnum – the unique reference number of one of the more than 13,000 citations listed in AZGeoBib.  Rarely will you use this parameter in your search.

Authors – Last names and initials of the authors of a report, manuscript or map.  To input names, place the last name first, followed by a comma and then initials.

Example.  Author Search:    Spencer, J. or Spencer, J.E. will yield 148 entries for Jon E. Spencer (AZGS).  Spencer J will yield a blank page.  SYNTAX Rules!

Date Published (datepub: in years A.D.) – This one is self-explanatory, and the mathematical notation works as you would imagine, too.

Title – A word or words found in the title of the material you are looking for.  The more specific you are the better your result, but be forewarned you can go too far. 

For example, a search on the Mormon Volcanic Field will not yield work on the Mormon Mountain Volcanic field, and visa versa.     Do not use quotes! 

Citation – The name or identity of the publication.  

For example, a citation search of Geological Society of America Bulletin yields 322 results.  A search of GSA Bulletin yields zero results.

State – The correct state abbreviation must be used.  AZ is Arizona, CA is California, NV is Nevada and so on.  Please note there are a bare few entries from other states.

Province – This refers to Arizona’s three physiographic provinces:  Basin & Range (BR or br), Transition Zone (TR or tr) and Colorado Plateau (CP or cp).  This parameter only recognizes the parenthesized terms. 

Example:  A Province search of cp yields 2834 results.  A search of Colorado Plateau yields zero results.

Counties – This can be a fruitful approach for those interested in the geology of a particular county.  You must, however, use the two-letter abbreviation for your county of choice; the two letter abbreviation for Yuma County is yu.   

Example:  A search of yu (Yuma County) renders 122 results.  A search using “Yuma” yields no results.  Syntax rules!

For a list of county abbreviations, see the first page of AZGeoBib Area Names.

Area – This is one of the more fruitful and specific searches that you can pursue.  The authors of AZGeoBib kindly included about 500 area names from throughout Arizona.  See the PDF entitled, AZGeoBib Area Names for a complete listing. 

Comments -- This is not a fruitful search parameter.  Avoid it!.

Keywords -- See the keyword.txt file for a listing of hundreds of keywords used in characterizing AZGeoBib citations.  Ex: Arid, breccia, brine, aluminum, aggregate.

Basin  See the basin.txt file for a list of nearly 60 basins, some of which are subdivided into upper, middle and lower.

Watershed  See watershed.txt for a list of 15 watersheds that can be searched in AZGeoBib.
