Query: Introduction to Linguistical Errors in Spanish

I am sorry, this book has so many errors! The history of the language was interesting, and it does teach a lot of different points...however, there are typographical erros on about every 2nd or 3rd page! It seems like it wasn't proofread before it went to print.Furthermore, you cannot say "del el" together, it is redundant...many errors like this were committed, and students will be learning the wrong way.Also, some words are used that do not exist, it is just a slang or lazy pronunciation, but it shouldn't be written that way.Finally, I am not sure if the section on vulgarities was really necessary or appropriate for a classroom...
