ECREL USER'S GUIDE
Using the ECREL Search Features
Welcome to the Electronic Cultural Resource Evaluation Library (ECREL) Search Tool. This tool allows
you to search for electronic copies of a wide variety of documents used for evaluating the National
Register eligibility of properties.
There are three types of searches you may perform:
1. Content Search
search for a word or
phrase contained in the
document.
2. Metadata Search
search by title, author,
publication date, area of
significance (from
National Register
Bulletin 16A),
repository, geographic
location, and/or
keyword.
3. Combined Search
use the search fields
alone or in combination.
For example, you may
search by author, by
author and area of
significance (AOS), or
by author, AOS, and a
word or phrase.
Click on a search type above or in the Table of Contents to learn more about that type.

Content Search
Content searching uses
the Verity search engine
to find a word or phrase
in a published document.
For example, enter the
word fishing in the
context search box and
click the search button.
A list of all documents
containing the word
fishing will be displayed.
The list may include
some documents that are
clearly related to fishing,
and others that may not
be so obviously related.
If the phrase fishing
industry is entered, a
much shorter list of
results is returned.
This type of search is commonly used for Internet searches. It is very powerful because it does not require
prior categorization and allows for greater searching flexibility than metadata searching.

Combined Search
A combination of metadata and content searching can be used. For example, a content search on Civil War
will yield all documents containing that phrase. If the Mid Atlantic region is also included in the search,
only documents associated with that region and also containing the phrase Civil War will be returned.
Whenever more than one search criterion is used, the syntax is:
value1 AND value2 AND . . .
In other words, only documents that meet all the specified criteria are retrieved. In general, the more
criteria specified, the fewer the results.

Definitions
Title Enter the title of document, usually the descriptive name assigned by
the author.
Author The original authors of the document.
Publication Date Date the document was published. If the document is a Multiple
Property or other National Register nomination form, it is the date the
form was written.
Area of Up to five areas of significance (from National Register Bulletin
Significance 16A) that are associat ed with the properties discussed in this
document.
Repository Usually, the name of the agency that is the primary repository for the
document. Some documents in ECREL were captured by
downloading from websites. In this case, the Repository name is the
URL for the document source.
Region Geographic region in the United States as defined by the National
Park Service.
County If the document is associated with a particular county, the name of
the county is recorded here. May be blank.
State The state with which the document is most closely associated; if the
document is not associated with a particular state, this field may be
blank.
City If the document is associated with a particular city, the name of the
city is recorded here. May be blank.
Document Type Documents are classified into one of the following document types:
Historic Contents, Multiple Property Submission, National Register
Nomination, and Administrative Record.
Keyword Keywords for a document may be assigned to ensure that properties
discussed in the document will be linked with specific associations,
events, time periods, attributes, etc. Generally, keywords are used
only if they are not already captured elsewhere (e.g., Area of
Significance), or do not appear in the document content.

Metadata Search
What are metadata?
Metadata are "data about data." In ECREL's case, they are data about documents and include things
like author and title. When documents were entered in ECREL, metadata were defined for them.
You may use any one or combinations of the following metadata attributes to search for documents:
Title
Enter a document title or part of a title. If you are not sure of the title, try entering one word from the
title. For example, entering `village' in the title search will return "The Culebra River Villages of
Costilla County Colorado" as well as "MD Suburbanization Colonial Village."
Author
Enter one or more names. As with title, a partial name (e.g., Brown) will work.
Publication Date
You have three search options. First enter a date -- you may enter a year (e.g., 1995) or a
specific date (e.g., 5/3/1995) -- then select one of the following:
· EQUALS searches for documents with the exact publication date you
specified;
· GREATER THAN OR EQUAL searches for documents published on
or after the date specified;
· LESS THAN OR EQUAL searches for documents published before or
on the date specified.
Area of Significance (from National
Register Bulletin 16A)
You may select one or more areas of
significance. Use the scroll bar to
view the entire list.
Region, State, County
You may select one value only for
each of these.
City
You may type in the name of a
specific city.

Document Type

Keyword
Keywords have been assigned for some documents. View the list to see keywords currently in
use, and then type one or more separated by commas in the box. (Note: Content searching is
usually a more effective method than keyword searching.)
