online (preferred over the hyphenated form on-line)
APA 6th, WNWD, and CMS 15th, and specify on-line as the proper form of an adjective preceding its noun. However, NCTE journals use the closed form, online. IRA writers and editors should use online for the sake of consistency with our former electronic journal, Reading Online.

online bookstore
Note this change in IRA style: "online bookstore" will no longer routinely be capitalized.

Online Computer Library Center = OCLC

online directory

Online Marketplace
  1. The term Online Marketplace constitutes the name of IRA's e-commerce site and should therefore be capitalized in most applications. The phrase is lowercased only when used explicitly as a generic term: IRA's Online Marketplace, like any other online marketplace, invites users to choose among a wide variety of products.
  2. The term Marketplace, when used as a shortened form of Online Marketplace, should also be capitalized.

on-screen (adjective preceding noun)

on site / on-site
This term is hyphenated as an adjective preceding the noun it modifies (an on-site inspection, on-site services). In other uses it is left open (the services are delivered on site). Thus, “Attendees who fail to preregister by March 3 must register on site. On-site registration will begin at 8:00 a.m. Saturday, May 8, 2011.”
