To know when the textbook was published, and to copyright it.
Knowing a textbook's copyright date helps readers understand how current the information in the book is. A more recent copyright date indicates that the content has been updated to reflect the latest information or research in the field. Conversely, an older copyright date may mean that the information in the textbook is outdated.
The reader might not understand the complex language, or might get bored easily. Using language that engages the reader and makes them want to read on is good to use. Hope this helps :)
I've usually seen it as 'Z' but that might vary between different textbooks.
yes if you go to classzone.com and they have it you might have to pay for it but you should be able to look at it online or if you have an eBook you just might have to pay
