Midlist

Midlist is a term in the publishing industry which refers to books which are not bestsellers but are strong enough to economically justify their publication (and likely, further purchases of future books from the same author). The vast majority of total titles published are midlist titles, though they represent a much smaller fraction of total book sales, which are dominated by bestsellers and other very popular titles.

Authors who consistently publish profitable but not bestselling books are referred to as Midlist authors.
