– If the user has access to a link resolver – What the URL is for the link resolver
Some services, like EBSCOhost, have an administrative module that allows the customers to input information on their link resolver. Other services, such as CrossRef, have no admin module and thus need to discover the link resolver information another way. They do this through the use of a cookie on the user’s browser. This cookie, if it exists, indicates that the user does have access to a link resolver and the content of the cookie is the link resolver’s URL.
The trick is getting the cookie written in the first place. Web servers can only read cookies that they have written; therefore, a mechanism is needed to have the resource (e.g., CrossRef) write the cookie. To accomplish this, some OpenURL resources will have cookie pusher scripts on their site. These scripts are normally activated from the library’s online resources web page. Activation of the cookie pusher scripts is achieved by including icons for the OpenURL-enabled resources on the web page. The URL for the icons is really a link to the cookie pusher script for that site. The act of displaying the icon pushes the cookies to participating resources.
In most cases, the cookies have a life span of a day or so; therefore, users must access their online resources through the library’s website to have LinkSource with A-to-Z active.back to top
