This is the link to the public profile of Darrell Ulm (Darrell Raymond Ulm) at Drupal.org listing Open Source projects, written mainly in PHP, MySQL for the Drupal content management system project.
Some of the projects include the Google Book project, https://www.drupal.org/project/google_books, which links up to the Google's project to archive book information. The module allows many options and ways to pull bibliographic information into Drupal text fields. This is a filter module so information is retrieved based on ISBN, ISO or other search, by title, or even by text. Individual entries can be displayed with different fields which can be set on a per item basis. There are also default settings for how to display data in general. Because there is a limit to the amount of book items that can be accessed in a time period, users can get authentication codes to allow accessing more data.
The IP Path Access module, https://www.drupal.org/project/ip_path_access, allows site administrators to restrict specified paths to only specific IP or IP ranges. These can include administrative pages, or any page as needed without having to restrict an entire site. There are also options for bypassing this access control by Drupal user role permissions.
Other modules contributed to include, Site Map, Filefield Role Limit, Sunlight Congressional Districts, and one Drupal Core patch.
