| There are four rows related to Karel++ ... This is a single book, and its ISBN should be 0-471-13809-6. It has four authors, and that is the reason for the four rows (can you say "redundant data"?). My guess at the reason for the distinct ISBNs is that Excel was in an auto-increment mode and "helped" me when I didn't need "help". //Fixed @ 20:41, 5/1/03 |
| A similar error occurs on line 70, where the ISBN should be the same as in line 69, ending in a '3', not a '4'. //Fixed @ 20:41, 5/1/03 |
| A different error -- this one apparently a pure typo -- can be found in line 115. A double '3' should be just a single '3', so the correct ISBN is 0-07-232204-7. //Fixed @ 20:41, 5/1/03 |
| The original Excel spreadsheet had some useless extra worksheets. I have now removed them. For those who copied the spreadsheet before 11:00 PM Sunday evening, April 27, there should be only five worksheets. Those that belong are named Pubs, Branches, Sales, Customers, Books. |
