An open textbook is an openly-licensed textbook offered online by its author(s). The open license sets open textbooks apart from traditional textbooks by allowing users to read online, download, or print the book at no additional cost.
For a textbook to be considered open, it must be licensed in a way that grants a baseline set of rights to users that are less restrictive than its standard copyright. A license or list of permissions must be clearly stated by the author. (Source: Varied Characterizations of Open Textbooks by Open Access Textbooks)
This tab highlights sites of materials in the public domain.
Public domain means there is no copyright attached to these materials. This term can refer to both historical resources whose copyright has expired as well as to modern works whose creators have released their materials into the public domain and waived copyright.
Please note that open access materials are NOT necessarily openly licensed. In general, you can link to open access materials, but you must check each site's terms of use for any further copyright or usage restrictions (e.g. restrictions on downloading or making copies of materials).
Open access (OA) refers to online research outputs that are free of all restrictions on access (e.g. access tolls or subscriptions). Open access can be applied to all forms of published research output, including peer-reviewed and non peer-reviewed.
