I've defined a library of JavaScript files and CSS files required for my module to function using hook_library().

How do I go about loading this library on node/edit pages?

    Not sure why I've been voted down for asking this question. Clearly I looked at the docs first.

I would call drupal_add_library() in a hook_form_alter() implementation, like this:

function MODULE_form_alter(&$form, &$form_state, $form_id) {
  if (isset($form['#node_edit_form']) && $form['#node_edit_form') {
    drupal_add_library('MODULE', 'LIBRARY');
  }
}

This should ensure the library is loaded whenever a node form is displayed.

And using hints from Berdir to use hook_form_BASE_FORM_ID_alter and from kiamlaluno to use #attached:

function MYMODULE_form_node_form_alter(&$form, &$form_state) {
  $form['#attached']['library'][] = array('MODULE', 'LIBRARY');
}

  • Doesn't answer how I then load that on node/edit pages? I'm looking for best practices here as there are always multiple ways of doing things?

    Note: You can use MYMODULE_form_node_form_alter() in Drupal 7.

If you are modifying, or outputting a form, you can use the #attached attribute, which is described as "allows loading of CSS, Javascript, libraries, or custom types when the form is built".
