Starting in VuFind 2.3, content-loading capabilities (for retrieving cover images, reviews, etc. from third-party APIs) were significantly refactored to rely on plugins.

Cover drivers are used for retrieving cover image data. They accept an array of ID values and return the URL to an image. Building a new plugin usually consists of setting some flags in the constructor to indicate which types of identifier are supported, then building a method to convert those identifiers into a valid URL.
