The Charter of the Forest of 1217 is a charter that re-established for free men rights of access to the royal forest that had been eroded by William the Conqueror and his heirs. Many of its provisions were in force for centuries afterwards. It was originally sealed in England by the young King Henry III, acting under the regency of William Marshall, 1st Earl of Pembroke. It was in many ways a companion document to Magna Carta. The Charter redressed some applications of the Anglo-Norman Forest Law that had been extended and abused by William Rufus.

Learning commons, also known as scholars' commons, information commons or digital commons, are learning spaces, similar to libraries and classrooms that share space for information technology, remote or online education, tutoring, collaboration, content creation, meetings, socialization, playing games and studying. Learning commons are increasingly popular in academic and research libraries, and some public and school libraries have now adopted the model. Architecture, furnishings and physical organization are particularly important to the character of a learning commons, as spaces are often designed to be rearranged by users according to their needs.

A tool library is an example of a Library of Things. Tool libraries allow patrons to check out or borrow tools, equipment and "how-to" instructional materials, functioning either as a rental shop, with a charge for borrowing the tools, or more commonly free of charge as a form of community sharing. A tool library performs the following main tasks:Lending: all kinds of tools for use in volunteer projects, facility maintenance and improvement projects, community improvement events, and special events. Advocacy: for the complete and timely return of all borrowed tools, to guarantee the long-term sustainability of available inventory. Staff also seeks compensation for lost tools and tools returned late. Maintenance: performing routine maintenance and repairs on all equipment to ensure good condition and to extend the lifespan of the inventory. This function is typically performed by volunteers and community service workers. Education: Some tool libraries also provide educational classes. Vancouver Tool Library and Community Access Center (VTLCAC) in Vancouver, Washington offers individual project support and classes on woodworking and basic car maintenance

Popular in the French-speaking world, toy libraries are called ludothèques.

The tragedy of the anticommons is a type of coordination breakdown, in which a single resource has numerous rightsholders who prevent others from using it, frustrating what would be a socially desirable outcome. It is a mirror-image of the older concept of tragedy of the commons, in which numerous rights holders' combined use exceeds the capacity of a resource and depletes or destroys it. The "tragedy of the anticommons" covers a range of coordination failures including patent thickets, and submarine patents. Overcoming these breakdowns can be difficult, but there are assorted means, including eminent domain, laches, patent pools, or other licensing organizations.

The tragedy of the commons describes a situation in economic science when individual users, who have open access to a resource unhampered by shared social structures or formal rules that govern access and use, act independently according to their own self-interest and, contrary to the common good of all users, cause depletion of the resource through their uncoordinated action. The concept originated in an essay written in 1833 by the British economist William Forster Lloyd, who used a hypothetical example of the effects of unregulated grazing on common land in Great Britain and Ireland. The concept became widely known as the "tragedy of the commons" over a century later after an article written by Garrett Hardin in 1968.
