Giải đáp mọi thắc mắc về Word 97/2003/2007

You use mail merge when you want to create a set of documents, such as a form
letter that is sent to many customers. Each letter has the same kind of
information, yet the content is unique. For example, in letters to your
customers, each letter can be personalized to address each customer by name. The
unique information in each letter comes from entries in a data source.
The mail merge process entails the following overall steps:

1. Set up the main document. The main document contains the
   text and graphics that are the same for each version of the merged document —
   for example, the return address or salutation in a form letter.
   
2. Connect the document to a data source. A data source is a
   file that contains the information to be merged into a document. For example,
   the names and addresses of the recipients of a letter.
   
3. Refine the list of recipients or items. Microsoft Office
   Word generates a copy of the main document for each item, or record, in your
   data file. If your data file is a mailing list, these items are probably
   recipients of your mailing. If you want to generate copies for only certain
   items in your data file, you can choose which items (records) to include.
   
4. Add placeholders, called mail merge fields, to the
   document. When you perform the mail merge, the mail merge fields are filled
   with information from your data file.
   
5. Preview and complete the merge. You can preview each copy
   of the document before you print the whole set.
   

You use commands on the Mailings tab to perform a mail merge.
