What is the correct syntax for a DynaMed Search Persistent Link?

There are several types of persistent links available in DynaMed, such as navigation, article and search persistent links. By utilizing DynaMed persistent link URL syntax, institutions have a seamless solution for integrating DynaMed content.

DynaMed persistent links always begin with this base URL:
http://search.ebscohost.com/login.aspx?direct=true&site=dynamed

Navigation Persistent Link

You can use persistent links to navigate to different pages in the DynaMed interface like the home page as well as the browse by letter or browse by category sections.

  • Home Page Persistent Link
    By using the DynaMed base URL you will be directed to the DynaMed home page.

    For Example:
    http://search.ebscohost.com/login.aspx?direct=true&site=dynamed

  • Browse by Letter Persistent Link:
    By adding “&letter=(insert letter in the alphabet A-Z)” to the end of the base URL you can navigate to the alphabetic section in the browse for list in the DynaMed interface.

    For Example:
    http://search.ebscohost.com/login.aspx?direct=true&site=dynamed&letter=A

  • Browse by Category Persistent Link:
    By adding “&expandCat=” to the end of the base URL you can navigate to the Browse by Category section in the DynaMed Interface.

    For Example:
    http://search.ebscohost.com/login.aspx?direct=true&site=dynamed&expandCat=

Article Persistent Links

To link to a specific article, the link must include an article ID, a DynaMed-assigned number that directly corresponds to a disease, condition, or drug record within DynaMed.

You can see the persistent link for any disease, condition, or drug record in the DynaMed interface by clicking on the icon P-link icon in the column on the right-hand side of the summary.

Search Persistent Links

You can create two types of persistent links to searches that will execute a search in DynaMed. The first type is a ‘Browse Topic’ persistent link and the second type is a ‘Search Text’ persistent link. 

  • Browse Topic Persistent Link:

    By adding “&alphaTerm=(your search term(s))” to the end of the base URL you can execute a Browse Topic search in DynaMed for the desired search term(s). If you are searching multiple terms, these would be separated by a ‘+'.

    For example:
    http://search.ebscohost.com/login.aspx?direct=true&site=dynamed&alphaTerm=Brain+tumor

    The above persistent link browses the DynaMed topic list for the term “Brain tumor.”

  • Search Text Persistent Link:

    By adding “&term=(your search term(s))” to the end of the base URL you can execute a Search Text search in DynaMed for the desired search term(s). If you are searching multiple terms, these would be separated by a ‘+’.

    For example:
    http://search.ebscohost.com/login.aspx?direct=true&site=dynamed&term=Brain+tumor

    The above persistent link searches the DynaMed Text for the term “Brain tumor.”

  • Capturing a persistent link to a search in the DynaMed Interface:

    To see a persistent link for any search (Browse Topic or Search Text) executed in the DynaMed interface, click on the persistent link icon P-link icon to the left of the text size icons.

    For example:
    persistent link - search

Adding Authentication Access to Persistent Links

You can add an authentication method to your persistent link. DynaMed offers several different ways to authenticate persistent links. This is achieved by adding authentication abbreviation(s) after “authtype=” Authentication will occur in listed order.

Methods of Authentication

  • IP Address authentication (ip) is the traditional method of identifying users requesting access to vendor databases. Users gain access based on their computer or site's IP address (numerical address).
  • Cookie authentication (cookie) tells DynaMed to write a cookie so that users do not have to key in authentication information every time they log in.
  • Referring URL authentication (url) provides access to DynaMed from a secure home page on the institution's web server. This identifies users by the originating URL (the page from which they came) and eliminates the need for user IDs. DynaMed validates the user if they are coming from an approved URL. If a user is trying to log in from a different URL, the system will not authenticate.
  • User ID and Password authentication (uid) can be useful to users who access DynaMed remotely. The library administrator can provide users with a user ID and password, providing instant access to DynaMed from their home or school computer.
  • Patterned ID authentication (cpid) provides access to DynaMed via a library card or bar code number. If the number entered does not match an ID set up by the library administrator, access is not permitted. The administrator can decide which characters are significant and compare up to 30 characters if needed.

Examples:

http://search.ebscohost.com/login.aspx?direct=true&authtype=ip,uid&site=dynamed&term=[ENTER_TERM]

The above persistent link searches for a specified search term and uses the IP authentication method first, but will prompt patrons for a user ID and password should the patron be accessing from an unrecognizable IP address.

http://search.ebscohost.com/login.aspx?direct=true&authtype=cookie,url&site=dynamed&term=[ENTER_TERM]

The above persistent link searches for a specified search term and uses the cookie authentication method first, but will use referring URL should the patron not have a DynaMed cookie.

Note: You may also include proxy server settings in your DynaMed persistent links. For more information about this authentication method, please see How do I configure a proxy server for use with DynaMed?
