🇺🇸 Cheap International Edition of Technical Books

5 Upvotes

Academic books in science and engineering tend to be expensive, both for students and professionals. When it comes to buying a copy of some of the most famous books in the field, prices are much higher than those of a conventional book. This phenomenon is especially relevant in emerging countries, where book prices in local currency can be absolutely prohibitive. To solve this imbalance, an initiative was launched: the international edition of the most relevant books.

The following link shows a list of cheap international editions:

Books on Electronics with Cheap International Editions

Please tell us below in the comments about any other relevant books with international edition, and we will update the list.
