First, you apply for an NLS account. A doctor will fill a part of the application. You mail it in, they'll evaluate it, if you get appproved they'll call you amd you start from it.
I'm sure it'll depemd by state, but there are some basic players you can get on loan.
You'll get a catalog every few months, in large print, and can request the audiobooks you want. They will mail the cartridges to your address, and you'll just drop them in a usps mailbox to return within 45 days.
You'll also get a URL for online bard account. The mobile app exists for iOS and android, and it's awesome. Download what you want, listen to whenever, keep if you like and have space.
And you can use also third party players like Victor.
On both NLS pkayers and BARD app you can set the speed up to 300%.
That is the major difference to other formats.
Bookshare is what a lot of people use too.
RNIB and many regular libraries use Overdrive. Audiobooks in that will work up to 2x speed, and the books will have an expiry date.
No harm in using multiple formats.
NLS books have a copy protections. (So much for Marrakesh treaty)
