Hello, serials folks.  Have any of you seen the December 2011 issue of Career Development Quarterly published by National Career Development Association?  It is numbered volume 59 no. 6, but is a quarterly title and clearly states inside that it is a quarterly title still.  The way the pattern works on this one is that the volume begins with September and ends with June.

This seems to be happening lately with several titles.  I guess I should contact the publisher to see what the problem is.

Thank you.

Sincerely,
