Campbell 7th

It was brought to my attention that there is a fairly serious error in some copies of the Campbell 7th edition. It doesn't appear to be present in the 6th edition.

In figure 38.4 (The development of Angiosperm Gametophytes), earlier copies of the 7th edition have the haploid and diploid labels reversed. It SHOULD be labeled so that the microsporocyte, megasporangium, megasporocyte and integuments are DIPLOID, and all the other structures are HAPLOID (except the micropyle, which is a gap and so is neither haploid nor diploid!)

As an aside, it can be tricky in the US to tell what printing a book is. However for many books there is a simple code on the rear of the title page that gives you the necessary info. In Campbell you'll find this on page ii just above the Benjamin Cummings logo. You are looking for a string of numbers like:
1 2 3 4 5 6 7 8 9 10 -VHC - 08 07 06 05 04
By taking the lowest numbers you get the printing and year (for some odd reason these numbers are not always in order). So the book I'm looking at was the first printing in 2004. Another copy I looked at in the Bio1B office did not have this mistake and was labeled:
4 5 6 7 8 9 10 - VHC - 08 07 06 05
or the 4th printing from 2005.

So now you know. I suppose if you wanted to get maximum value for your dollar in a used textbook store you would look for later printings hoping that mistakes had been corrected.
