Formats & Editions
Hardcovers are durable and ship first, but paperbacks are lighter and cheaper. For collectors, look for sewn bindings, acid‑free paper, and dust‑jacket design; for students, prioritize durable spines and wide margins for notes. eBooks excel for portability and instant access across devices. Audiobooks turn commutes into reading time, and many nonfiction titles benefit from author narration or supplemental PDFs.
- DRM: vendor‑locked files may limit sharing; DRM‑free stores and public domain editions offer flexibility.
- Special editions: annotated, illustrated, or with bonus chapters can be worth the premium for favorites.
- Textbooks: check for international editions or earlier versions with identical content at lower cost.
