These two materials are different kinds of the book made to suit the taste of the masses. The mass paperback books are like two inches smaller than the paperback ones, either in length or breadth. The paperback books are more expensive than mass paperback. The reason for the paperback being more expensive is most likely due to the fact that it was harder and more quality inner sheets and back covered paper than the mass paperback books. The paperback has more spacing between the lines of the book and looks easier to use.
The paperback also looks similar to the hardcover books with almost exactly the same illustrations and layout. However, the mass paperback looks smaller, and with close line spacing, it does not look similar to the hardcover book. Mass market paperbacks are easily available and accessible for buying by the general masses, as it is available in convenient stores, retail stores, and gift shops. On the other hand, the mass paperbacks are easily available to buy; they are usually gotten from bookshops and libraries.
The main difference between a paperback and a mass paperback is that paperback can be bought from bookstores, book dealers, distributors, and resellers. Mass market paperbacks, on the other hand, are generally located in drugstores, grocery markets, and airports. Paperbacks are printed on high-quality paper. They usually contain illustrations and a French flap.
A mass-market paperback is published on low-quality paper, and it is often not illustrated. It is smaller, and it does not have a French flap. Paperback is pricier, and it is printed with the mindset of the publisher that the reader has the same reading experience they obtain with hardcovers but minus the heavy cover.
If you have an experience of purchasing a book online and was given the option of a paperback or a mass-market paperback, there is a high chance that you will choose either of the two as you would think they are just the same. But truthfully, they are completely different from each other. A paperback is made of high-quality paper that usually has the same illustrations, size, and pagination of their hardcover edition.
This is also more expensive than the mass-market paperback and usually is available in bookstores, distributors, and book dealers. A mass-market paperback, on the other hand, is made of low-quality paper, smaller in size, and usually, do not have illustrations. It is also present in a bookstore but is common to see near the checkout lanes in supermarkets, drugstores, and airports.
A lot of people think that these two are the same because they are very similar to each other. The main difference is only soft-binding. Trade paperbacks may have some differences with the paper used or the type of cover used. This is also priced higher as compared to mass-paperback.
If you are very particular about the books that you want, you may spend a little higher and choose the paperback over the mass-produced paperback but if what truly matters to you is the story that you are going to read, any book will be fine. What matters is you will be able to read everything clearly.
