2 approaches:

1.  Do Mail Merge using Word - with the Word mail wizard it prompts you to
select your data source and you simply browse to the Access table or query  
(no need to put things in excel - that is just a separate step...)

2.  Create a Report; embedded in the Report Wizard making capability is to
use labels as well.

I have done / and do both.  When someone is doing alot of Access things -
like looking at forms/reports/etc...and just one of the things they need is
also labels - I use number 2 approach.

On the otherhand if someone is really only doing labels - and simply uses
Access to keep the data organized...I use approach 1.
