About CDs & MP3s
When an item on Mackin.com indicates MP3, that means that it is an MP3 formatted CD instead of an electronic file or download. MP3 stands for Moving Picture Experts Group (MPEG), Audio Layer 3. The total file size is smaller, without sacrificing audio quality, allowing for more storage. While a regular audio CD holds 74 minutes of audio, MP3-CDs can hold up to 12.5 hours of audio. Also, if the primary use of the audiobook is to be played on a MP3 device, it is the most practical as the longer tracks create less file ‘clutter’ and MP3-CD audiobooks cost less.
Publishers expect that once a student is finished, he/she will delete the content from their device. However, once the MP3/CD is returned to the library, the next student may check it out and upload it to their device, even if the last student is not finished with the content on their device.
Library Ed. vs. Retail Ed.
Compared to a retail CD/MP3 audiobook, usually, the library edition will have more durable packaging and free lifetime replacement of discs and cases. Contact us at email@example.com for details.
There is no limit to the number of times content can be loaded, as long as the school or library is not loading the content.
The only person that is allowed to load the audio is the patron/student. The library cannot load the audio for the patron/student. It must be done at home.
When a “physical” audiobook (CD, MP3-CD) is purchased for a classroom or by a library, it can be lent to the students or patrons. But only one student or patron can borrow it at a time (one book, one user basis). The first one will have to bring it back to the school or the library for the second student or patron to be able to check it out. The students can listen to the audiobook on any device of their choice. It is expected that the files are deleted once the patron or student is done with it.
