How to Search the Database
The NSGL database is updated on a monthly basis. Full bibliographic citations and abstracts (when available) are provided for each document in the database. In addition, many documents are being digitized and are available here as full-text PDF images. To view and print these electronic documents you must have Adobe Acrobat Reader which you download free of charge from our Search Form.

You may search the database by title and author, as well as other fields.  The asterisk (*) may be used for truncation purposes. For more detailed options, please see the Search Guide below. If you would like to search by Sea Grant institution or by type of publication, please use the appropriate NSGL code from the lists below (please note: the institution code must be followed by as asterisk; ie. MDU*). Newly acquired Sea Grant documents that are not included yet in the database are listed in the Recent Acquisitions page.

Boolean Operators

AND	Searches for records containing both of the words (narrows the 
	search).

	e.g.  lobster and aquaculture   will find only records 
	containing both lobster and aquaculture in the entry.

OR	Searches for records containing either of the words (broadens
	the search).

        e.g.  lobster or aquaculture   will find records with 
	lobster or aquaculture in the entry.

AND NOT Searches for records containing the first term but not the second.
	
	e.g.  lobster and not aquaculture  will find records with
	lobster in the entry but will not find anything on lobster
        aquaculture.

Truncation

The asterisk * may be used to truncate a search term.  (It's use is 
suggested in most cases.) 

	e.g.  fish*   will search for fish, fishery, fisheries,
	      fishing, fisherman, fishermen, etc.

Also use the asterisk when searching by institution code. 

	e.g.  WISCU*  will find all the publications from the 
	      Wisconsin Sea Grant Program   

Multi-field search

You may search for terms from two different fields.  After typing in
your search term/phrase, you may indicate which field you would like
to search by selecting it from the pull-down menu in the field box. The
fields that can be searched in the NSGL database include:

	Title
	Author
	NSGL document number
	Other Report Number (one the institution assigns)
	Sea Grant Institution 
	Publication Year 
	Publication Type
	Full Text

Report Number Search

 
The quickest and most efficient way to find a particular publication
is to search for either the NSGL document number (type the number in the
term box and click on NSGL document number field in the pull-down menu
below) or the institution's report number (other report # field).  Please
note that the number must be typed exactly (with correct spacing and
dashes) as it appears in the database.  Also if the institution's number
was not supplied to us it may be missing from the database, so if you
don't succeed try another search method.

Publication Year Search

When searching for publication year use 4 digits (e.g. 1995)
in the term box and select the publication year field from the pop-up
menu.

Phrase Search

You may search for phrases on one line in the search term box.  Be sure
that the words are in the exact order or you will have trouble locating
the desired information.

	e.g.	SEARCH TERM		FIELD SELECTED

		law of the sea		title (or full text)

		fisheries management	title (or full text)

		narragansett bay	title (or full text)

Author Search

Authors can be searched a couple of different ways.  You can put
the author's first name in the first term box and the last name in the 
second term box and search the author fields. 



	e.g.	 SEARCH TERM		FIELD SELECTED

  		 scott			author

		 nixon			author


Or you can search the author's last name and the institution code (if
known). This method will also find documents where the author might have 
used a nickname or a first initial (the first method will not). 
However, it will also find documents by other authors with the same 
last name from that program, which you must just disregard.
 
	e.g.     SEARCH TERM		FIELD SELECTED

		 nixon			author

		 riu*			institution code


If you are looking for documents that were co-authored, put their last
names in each of the term boxes and search either the author or 
full-text fields using the "and" operator.

Hint:  Using full-text to search for authors will also find papers from
proceedings and book chapters that they've written, as well as works
edited by them.

Advanced Searching

For those desiring more flexibility or additional search terms, you may
now string 2 or more words in each term box and link them with the search
operator of your choice in the pull-down menu to the right of each term
box. The default (word or phrase) indicates ADJ (adjacent) so no
change is necessary during simpler searches.  Search terms must be
separated by a space or a comma. The search operators allowed are:

 	AND     (two or more terms)

	OR      (two or more terms)

	AND NOT (two terms only)

        NEAR    (two terms only)



Example 1 (to search on a topic using several terms)

      TERM 1    shrimp oyster clam shellfish   Search Operator   "OR"

      FIELD 1   Full text

AND

      TERM 2    aquaculture farming            Search Operator   "OR"

      FIELD 2   Full text

The above search will find everything on shrimp aquaculture, shrimp
farming, oyster aquaculture, oyster farming, etc.

Example 2 (to search for a particular document or topic by a specific
          author)

      TERM 1    biomass community microbiota   Search Operator   "AND"

      FIELD 1   Title

AND
      TERM 2    Fazio		     
      
      FIELD 2   Author

The above search must have all three words (term box 1) in the title
and Fazio must be one of the authors.

Additional Features (to further refine your search)


Two new features have recently been added that will help you further
refine your search. These new features provide added flexibility in
searching by freeing up the main search term boxes.

(1) The first feature allows you to limit your search by range of
publication years. The default is "all years". If you would like to
search only selected years please use the pull-down menu to indicate
the years desired. This feature is especially helpful if you are looking for
the most current titles in a particular subject area.

Please note: The system goes back the number of years indicated starting
with the last full year completed. For instance, if we are in the middle of 2004 and you
wanted to search the "last 5 years", the years covered would include
2003, 2002, 2001, 2000 and 1999, as well as any portion of 2004 completed to date. Please
keep in mind that in any current year, the Library is often still acquiring documents
published in previous years. 

(2) The other new feature allows you to limit your search to documents generated by
either a particular Sea Grant Program or a group of Sea Grant Program's within a
particular geographic region in the United States. For instance, searching
the "Mid-Atlantic" region will automatically search documents from the Delaware,
Maryland, New Jersey, North Carolina and Virginia Sea Grant programs.

Limitations

Currently special characters and diacritics cannot be searched from this Z39.50 
server because they cannot be displayed correctly in HTML.

Publication year range searching is a feature we hope to make available 
at a later date. Currently you can search for a single (4 digit) publication
year only.



Helpful Hints

The search software is case insensitive (upper or lower case letters can be used).

Do not include stop words (such as prepositions, articles or
conjunctions) as search terms, unless they are part of a phrase.

When searching by publication type you must type the NSGL publication
type code twice (as shown in the publication type code list). The
software will not search single letters.

After 5 minutes of inactivity your search connection will time-out. If this happens
you will need to re-initialize the search form by clicking the "search the database"
button.
