Public Catalog

New Subject Browse Index Definitions

New subject browse index definitions have been added that display the entire heading as a unit with hyphens between terms instead of displaying individual terms separately.

For example, the browse heading for:

=650 \0$aCats$zUnited States$vCorrespondence.

will display in a single entry as:

Cats — United States — Correspondence

Rather than separate entries for Cats and United States.

Name subjects will continue to display as separate entries because additional work would be required for the heading to be punctuated correctly.

Advanced Search Limiters Enhancement

Advanced search limiters will no longer propagate to the basic search box in the catalog. Instead, the limiters applied to the search will appear underneath the search box where they can be easily cleared by clicking an x. On a small, mobile device, the advanced search limiters can be seen by clicking an x filter applied link.

The selected limiters will be applied to any search from the search bar until: * The user actively removes the filters from the search or * The user starts a new basic or advanced search from scratch.

Arabic and Right-to-Left Language Support for the catalog

New stylesheets and other changes to the catalog to allow for better support of right-to-left (RTL) languages, such as Arabic.

Also adds Arabic (Jordan) as a new supported language.

Ebook API integration

Evergreen 2.12 supports partial integration with third-party APIs provided by OverDrive and OneClickdigital. When ebook API integration is enabled, bibliographic records from these vendors that appear in your public catalog will include vendor holdings and availability information. Also, when a user is logged in, the public catalog dashboard and My Account interface will include information about that user’s checkouts and holds for supported vendors.

For API integration to work, you need to request API access from the vendor and configure your Evergreen system according to the instructions below. You also need to configure the new open-ils.ebook_api service.

This feature assumes that you are importing MARC records supplied by the vendor into your Evergreen system, using Vandelay or some other MARC import method. This feature does not search the vendor’s online collections or automatically import vendor records into your system; it merely augments records that are already in Evergreen.

A future Evergreen release will add the ability for users to check out titles, place holds, etc., directly via the public catalog.

Ebook API service configuration

This feature uses the new open-ils.ebook_api OpenSRF service. This service must be configured in your opensrf.xml and opensrf_core.xml config files for ebook API integration to work. See opensrf.xml.example and opensrf_core.xml.example for guidance.

OverDrive API integration

Before enabling OverDrive API integration, you will need to request API access from OverDrive. OverDrive will provide the values to be used for the following new org unit settings:

  • OverDrive Basic Token: The basic token used for API client authentication. To generate your basic token, combine your client key and client secret provided by OverDrive into a single string ("key:secret"), and then base64-encode that string. On Linux, you can use the following command: echo -n "key:secret" | base64 -
  • OverDrive Account ID: The account ID (a.k.a. library ID) for your OverDrive API account.
  • OverDrive Website ID: The website ID for your OverDrive API account.
  • OverDrive Authorization Name: The authorization name (a.k.a. library name) designated by OverDrive for your library. If your OverDrive subscription includes multiple Evergreen libraries, you will need to add a separate value for this setting for each participating library.
  • OverDrive Password Required: If your library’s OverDrive subscription requires the patron’s PIN (password) to be provided during patron authentication, set this setting to "true." If you do not require the patron’s PIN for OverDrive authentication, set this setting to "false." (If set to "true," the password entered by a patron when logging into the public catalog will be cached in plain text in memcached.)
  • OverDrive Discovery API Base URI and OverDrive Circulation API Base URI: By default, Evergreen uses OverDrive’s production API, so you should not need to set a value for these settings. If you want to use OverDrive’s integration environment, you will need to add the appropriate base URIs for the discovery and circulation APIs. See OverDrive’s developer documentation for details.
  • OverDrive Granted Authorization Redirect URI: Evergreen does not currently support granted authorization with OverDrive, so this setting is not currently in use.

For more information, consult the OverDrive API documentation.

To enable OverDrive API integration, adjust the following public catalog settings in config.tt2:

  • ebook_api.enabled: set to "true".
  • ebook_api.overdrive.enabled: set to "true".
  • ebook_api.overdrive.base_uris: list of regular expressions matching OverDrive URLs found in the 856$9 field of older OverDrive MARC records. As of fall 2016, OverDrive’s URL format has changed, and the record identifier is now found in the 037$a field of their MARC records, with "OverDrive" in 037$b. Evergreen will check the 037 field for OverDrive record identifiers; if your system includes older-style OverDrive records with the record identifier embedded in the 856 URL, you need to specify URL patterns with this setting.

OneClickdigital API integration

Before enabling OneClickdigital API integration, you will need to request API access from OneClickdigital. OneClickdigital will provide the values to be used for the following new org unit settings:

  • OneClickdigital Library ID: The identifier assigned to your library by OneClickdigital.
  • OneClickdigital Basic Token: Your client authentication token, supplied by OneClickdigital when you request access to their API.

For more information, consult the OneClickdigital API documentation.

To enable OneClickdigital API integration, adjust the following public catalog settings in config.tt2:

  • ebook_api.enabled: set to "true".
  • ebook_api.oneclickdigital.enabled: set to "true".
  • ebook_api.oneclickdigital.base_uris: list of regular expressions matching OneClickdigital URLs found in the 859$9 field of your MARC records. Evergreen uses the patterns specified here to extract record identifiers for OneClickdigital titles.

Additional configuration

Evergreen communicates with third-party vendor APIs using the new OpenILS::Utils::HTTPClient module. This module is configured using settings in opensrf.xml. The default settings should work for most environments by default, but you may need to specify a custom location for the CA certificates installed on your server. You can also disable SSL certificate verification on HTTPClient requests altogether, but doing so is emphatically discouraged.

Links to Other Formats and Editions

The record summary pages in the catalog will now link to other formats and editions of a title. The links will allow users to quickly jump to another format of the title or an edition written in another language.

Metarecord Search Improvements

This release brings several improvement to the Group Formats and Editions search.

  • Limiters on the advanced search page can now be successfully applied to Group Formats and Editions searches,
  • Electronic resources are now retrievable through these searches,
  • Paged navigation has improved.

Allow Metarecord Search by default

Before the TPAC, a site could configure the public catalog to use metarecord searching by default, via a configuration file. Here we bring that back.

A new setting called search.metarecord_default is present in templates/opac/parts/config.tt2 to enable this feature. By setting this to a true value (normally 1) the TPAC will silently include the #metabib search modifier in the search form on any interfaces that do not have a UI component that allows the user to control the setting.

RDA Improvements

  • Author fields are now normalized to strip ending periods so that authors from RDA and non-RDA records are collapsed in browse and facet headings.
  • All author/contributor roles will now display in the record detail page. Previously, some of the roles were omitted or were duplicated. Integration

Evergreen now integrates with Czech added content provider A new setting called obalkyknih_cz.enabled is available in templates/opac/parts/config.tt2 to enable this new feature.
