  Sure. There are two ways to do it. 

  An "A" record associates your name clare.galwaylibrary.ie
  with the IP address of  www.clarelibrary.ie, which is
  195.7.56.195. In a BIND configuration file

clare.galwaylibrary.ie. IN      A       195.7.56.195

  You can also associate clare.galwaylibrary.ie with
  the name www.clarelibrary.ie. This is known as a "CNAME". 
  In a BIND configuration file

clare.galwaylibrary.ie.	IN	CNANE	www.clarelibrary.ie.

  Note the position of the dots in the two example lines.
