The platform exists but it is probably not what you want: Library Genesis. Publishers insist on pushing paper-book characteristics like 'wear and tear' to digital copies in libraries so they can only be lent out a given number of times or a certain number of months after which they are 'worn out' and the library needs to buy a new copy. Here are some of the rules set by different publishers [1]:
Penguin Random House: one copy/one user, metered access: titles expire after 24 months, then library must repurchase
Hachette Livre: one copy/one user, metered access: titles expire after 24 months, then library must repurchase
HarperCollins: one copy/one user, metered access: titles expire after 26 checkouts, then library must repurchase
Macmillan: one copy/one user, libraries limited to 1 copy of newest titles for the first 8 weeks after publication, metered access: most titles expire after 24 months or 52 checkouts (whichever comes first), then library must repurchase
Simon & Schuster: one copy/one user, metered access: titles expire after 24 months, then library must repurchase
Ebooks are priced at 2 to 4 times the retail rice when sold to libraries.
A question to those working in publishing: where does the revenue end up? Is this another example of a rent-seeking scheme like Elsevier/Wiley et al. have been up to in scientific publishing or does it work like Spotify where at least part of the revenue goes to the authors?
