This detail of William Hogarth's "Industry and Idleness, Plate 1; The Fellow 'Prentices at their Looms" shows an industrious apprentice weaving while his master looks on from the doorway. The first pioneers and settlers in colonial Carolina did not learn in formal schools as many do today. Through informal learning, most colonial children learned what they needed to know to live: how to grow crops, build and maintain farms, and raise families. Many boys who were not going to become farmers learned other skills through apprenticeships, as this young man at his loom.
Public Domain is a copyright term that is often used when talking about copyright for creative works. Under U.S. copyright law, individual items that are in the public domain are items that are no longer protected by copyright law. This means that you do not need to request permission to re-use, re-publish or even change a copy of the item. Items enter the public domain under U.S. copyright law for a number of reasons: the original copyright may have expired; the item was created by the U.S. Federal Government or other governmental entity that views the things it creates as in the public domain; the work was never protected by copyright for some other reason related to how it was produced (for example, it was a speech that wasn't written down or recorded); or the work doesn't have enough originality to make it eligible for copyright protection.
