Hello,
.
First point is are you a regular student or Distance student.
.
If you are regular student then college will guide you about books to be taken.
College will suggest you the series and publisher information Which you can get them in book store.
.
Every college has there Own trusted publishers.
Some of the private medical colleges will have there Own books providing for students.
.
So, don't be worried about booms.
You will be well guided by the faculty about them.
.
Hope this was helpful.
Thank you
