Chapbook is also a term currently used to denote publications of up to about 40 pages, usually poetry bound with some form of saddle stitch, though many are perfect bound, folded, or wrapped. These publications range from low-cost productions to finely produced, hand-made editions that may sell to collectors for hundreds of dollars. More recently, the popularity of fiction chapbooks has also increased.
The genre has been revitalized in the past 40 years by the widespread availability of first mimeograph technology, then low-cost copy centers and digital printing, and by the cultural revolutions spurred by both zines and poetry slams, the latter generating hundreds upon hundreds of self-published chapbooks that are used to fund tours.
With the recent popularity of blogs, online literary journals, and other online publishers, short collections of poetry published online are frequently referred to as "online chapbooks," "electronic chapbooks," "e-chapbooks," or "e-chaps."
