Only "Some" books have a solution, and not in all editions, our priority is to publish the Solution along with the Book in its respective edition so that the problems of the book are consistent with the exercises solved in the solution.

If you only find the book in one publication, it is because we do not have the solution for that Edition; or maybe there is no such, but you should also look in another edition. To do this, just click on the name of the author of the book and you will be able to view all the editions that we have of it.

In certain books, mainly science, physics and chemistry; the solution of one edition can be used for others, since many of the problems that it brings are the same between one edition of the book and another, or they are simply in a different order.

Note that only the most recent editions have Solvers.

The vast majority of the solutions are in English, except for a few cases; as these files are created primarily for the English editions of the books.

Solvers in Spanish are generally files created by teachers or people other than the authors of the book, who are simply interested in solving all the problems in the book and creating a solution.

Likewise, if the Book is in English, it is because we do not have a digital or scanned version available in Spanish. But when we get it, we post it where the English version is.

Despite careful checks by our editorial staff, it may happen that occasionally parts of the e-book, such as sections, interviews, illustrations, are missing from the book, usually from older editions, as many of these files are scanned and this process may not have been completed.

Some supplements to the text, such as matlab files, additional source code, or some CD-ROM content, will not be available in all editions of the work.
