Chapbook vs zine vs pamphlet

All three are small, cheap, stitched or folded booklets. A chapbook is literary, usually poems or prose; a zine is self-published and can be about anything; a pamphlet is defined by its argument, often political or informational. The overlap is real and the edges are blurry.

Where they meet

A self-published poetry chapbook made on a photocopier is, physically, a zine. A political pamphlet of poems is all three at once. The words describe intention and tradition more than object: the same stapled booklet can be any of them depending on who made it and why.

Which word to use

If it is literary and you sent it to a press, call it a chapbook. If you made every copy yourself and it is personal or eclectic, zine is honest. If it exists to persuade or inform, it is a pamphlet. For the literary form, see what a chapbook is.
