BACKGROUND

URLs (Universal Resource Locators) are WWW addresses for electronic resources. These web addresses often contain special characters such as a blank or tilde which do not translate into the character set used by library catalogs such as CLIO. Catalogers must provide hexidecimal equivalents for these characters in order for the web address to function as a link in a web browser.

Hexidecimal equivalents for special characters in CLIO are:

blank		%20
tilde	~	%7E
underscore	_	%5F
broken bar	|	%7C

Procedure:

1. Input <hexidecimal equivalent> in the 856 field without spaces.

   Example:

A URL that appears as:

http://digilib.nypl.org:80/dynaweb/digs/wwm97255/@Generic__BookView

Must be input as:

http://digilib.nypl.org:80/d ynaweb/digs/wwm97255/@Generic%5F%5FBookView

Notes:

• Some special characters, such as the underscore, may require two hexidecimal equivalents.

• When the 856 is actually searched on a browser, the special character will redisplay.
