Display Logic Rules control the conditions for display of Alma Services in Primo VE's Get It and View It sections.  They are configured on the Discovery Interface Display Logic page in Alma Configuration > Fulfillment > Discovery Interface Display Logic > Display Logic Rules.  This page contains some optional recipes for controlling the presentation of e-Collections with DLRs that I-Share institutions may choose to configure.

How to Hide One e-Collection When a Specific e-Collection is Available

Goal: If a resource is in e-Collection X, don’t show links to e-Collection Y (or possibly several different e-Collections).

Why might you want to do this?

To give priority to X over Y. For example, e-Collection X may be lower cost than e-Collection Y, or e-Collection X may have better linking quality and reliability.  

This recipe requires you to create one Display Logic Rule (DLR).

 

How to define the DLRScreenshot of the Add Rule pop up in Alma.

The Example Rule in the steps below will hide "EBSCOhost GreenFile" if the full text is available in "EBSCOhost Academic Search Complete."

For this example, you can refer to the image at the right for steps two through seven. It is a screenshot of the Add Rule pop-up screen in Alma with the following fields: For user from groups, hide service (with a red asterisk), with, and with value. The buttons at the bottom of the pop-up read: Add, Cancel, and Add and Close.

1. Go to Alma Configuration > Fulfillment > Discovery Interface Display Logic > Display Logic Rules.

2. Click on Add Rule to create a blank rule. 

3. Click on the down arrow at the end of  hide service* drop-down and select Full Text.  This will populate more fields with drop-down menus below the hide service* field.

If desired, you can add multiple e-Collections to a rule. For example, the rule pictured below will hide "Counseling and Therapy in Video: Vol. 2," "Criminal Justice Database," and "EBSCOhost GreenFile" if the full text is available in "EBSCOhost Academic Search Complete."

    • Criminal Justice Database

Use the Interface option to hide a group of e-collections from the same vendor/interface company.

Just select Interface instead of Electronic collection in the with field for Full Text service.

For example, the rule pictured to the right of this text means: If the resource is in any EBSCOhost Interface e-collection, don't show CCC Get it Now Interface e-Collections. This might be useful because CCC Get it Now from Copyright Clearance Center e-Collections are more costly than EBSCOhost. The following selections were made in the screenshot:

  • For user from groups field is blank
  • hide service* field lists Full Text
  • with field lists Interface
  • with value* field lists CCC Get It Now
  • if exists service field lists Full Text
  • with field lists Interface
  • with value* field lists EBSCOhost 

 

 

OPTION 3 

You can also mix Electronic Collections and Interface variables. The rule pictured to the right of this text, will hide any other interface's e-Collections if the full text is available in EBSCOhost Academic Search Complete. Leaving the with value field blank will include all interfaces or all e-Collections.
