[Classweb-users] FW: QA76.76.O63

[Michael Borries]

QA76.76.O63 is listed in parentheses with a note to use QA76.77-.774.  I was under the impression that once the class had been changed, new editions of titles were to be classed in the new class number.  Is this correct?  If so, are the examples below simply titles that "slipped through the cracks"?

Hi Michael,
You told us a while back that QA76.76.O63 is no longer being used. But I keep getting new books, cataloged by LC, with that call number.
Case in point:
Understanding operating systems by Ann Mciver, 7th ed., ISBN 9781285096551, 2014
And even a 2015 publication:
Modern operating systems by Tanenbaum and Bos, 4th ed., ISBN 9780133591620.
Do I have to do original cataloging each time I get one of these books?
