Drinking Water Literature Database Help
Developed and maintained by the National Drinking Water Clearinghouse, a program of the NESC.
Selecting
search terms
You may search
the database by keyword, author, title, year of pulication, or source, or
by any combination of these categories.
Some categories
use the "Equals" method, which allows you to select one or more options
from a list. Other categories use the "Contains" method, which allows you
to enter a part of a word, a whole word, or a multi-word phrase separated
by spaces. The Keyword category allows you to search using either the "Equals"
or the "Contains" method.
Keyword
If you know the exact keyword and it is present in the keyword list, select
that keyword and leave all other entries blank. Then press "Search."
If you know
only a part of a keyword, or the keyword is not present in the keyword list,
select "Contains" and enter a part of a word, a whole word, or a multi-word
phrase separated by spaces. Then press "Search."
NOTE: If you
select "Contains," any words selected from the list of keywords in the "Equals"
section will not be included in the search.
