Carbon copies originated in the days before photocopiers or laser printers as a way to type multiple copies of a document at the same time. A piece of carbon paper was inserted between two regular pieces of typing paper, so that anything typed onto the first page, would also be transferred onto the second. If a copy of a document was being provided to multiple recipients, the letters “Cc” were typed under the signature at the end of the letter with the additional recipients’ name or names. This alerted the original recipient that other people were receiving the same information, and who those people were. Though we don’t need the actual pieces of carbon paper anymore, the abbreviation Cc is still used today in electronic communication to identify additional recipients of an email. The Cc field is one of three fields used to address an email. The “to” field should be used if your email is addressed to only one person. If you are sending the email to several people, you can put the additional addresses in the “to” field...or in the Cc field. Use the “to” field for all the addresses if the email is directed equally to all recipients, especially if all recipients are being asked to respond. Use the Cc field for additional addresses if the email is mostly directed to the main recipient, and the additional recipients are just being made aware of the information. Addresses in the “To” and “Cc” fields are visible to all recipients. If you don’t want recipients to be able to see the other people receiving the email, place addresses in the Bcc field.Bcc stands for “blind carbon copy”. To keep all recipients’ information hidden, put your own email address in the “to” field and all recipients in the ‘Bcc’ field.
