This module integrates Drupal with III/Millennium WebOPACs (library catalogs): you can import bibliographic records, or embed records in a node using the input filter. Imported nodes can have taxonomy terms created from the original record, a real-time holdings display, embedded book previews from Google Book Search and more.
The Admin Notes module creates a block that displays a textarea pre-filled with the existing comment for that specific page, if any.
Each comment is associated with a page.

Flexifilter is a module that allows non-coders to create their own, configurable custom filters. It is not limited to simple text replacement or regex replacement; it includes logic such as if() and while() statements, and is easily extendable by other modules. It is the best thing to hit Drupal since the potato.
