Three important advantages from these books: quality, variety and low price. You can find for a very good price, a wide range of topics in mathematics, physics and chemistry. For example, about topics in mathematics you may find:

The list if really long, so the diversity is huge and fascinating. From my opinion, every new book published from the MIR Editorial was carefully prepared, in order to bring in a didactic way all the necessary tools to solve and learn new topics.
Several webpages are dedicated to compile information about these books, for example:

Sadly, it seems like right now the MIR Editorial is in bankrupt. If so, it is a big pity to lose what it was known as an excellent Editorial of science books.
See you around.
