EBSCO's LinkSource requires EZproxy 2.0i (2003-03-09) or later.
EBSCO LinkSource requires the following database stanza in config.txt:
Title -hide EBSCO Full Text Finder
This database stanza should appear in config.txt before any other EBSCO database stanzas.
The Title directive's -hide option was introduced in EZproxy 3.2a (2005-03-28) and suppresses the database stanza from appearing in the generated menu. If you are using an older release of EZproxy, you should omit -hide.
