E-book licensing works differently from buying a physical copy, and the terms can meaningfully affect what you're actually allowed to do with a title.
Individual licenses are usually single-reader
A standard e-book purchase typically grants access to one reader on a limited number of devices — not for sharing across a team.
Organizational licenses scale by seats or usage
Multi-user access usually comes through seat-based licensing (a fixed number of concurrent readers) or site licenses covering an entire organization.
Check renewal and transfer terms
Some licenses are perpetual, others subscription-based. Before committing, confirm what happens if your team size changes or a license period ends.
If you're buying for more than one person, mention that upfront — the right licensing structure depends entirely on how the content will actually be used.
