A mechanism is presented for merging e-mail messages into a collated file. An e-mail message and its associated responses may be accessed and collated based on a selected pattern for responses. The set of e-mails may be collated into a single document with the responses associated with the particular message to which the response is directed. Using pattern matching operations in an iterative fashion, a response may be associated with the message that elicited the response whether the original message or a previous response. The form of association may be user selectable.
