I am wondering if it is a bad idea to use an old textbook, such as Differential and integral calculus, with examples and applications by George A. Osborne. This book was published in 1906 and there are no known copy right restrictions, which means students may use a free e-version if they would like to save money. On the other hand, hard copies are still available for sale.
To me, this book is very well written and contains all the basic materials that need to be covered in a traditional calculus course. Furthermore, it also contains a large number of examples, which is very helpful to the students. On the other hand, I am wondering if there is any issue with using an old textbook like this. For example,
- Are there any terminologies and notations that are considered outdated?
- Are there any new discoveries in the past 110 years or so that need to be included into the calculus course which were not found in an old book?
- What will my students and peers think about the idea of using an old textbook?
I personally do not know any teacher who uses such an old book as the textbook; but is it really a bad idea to do so?
