This report is part of the Web-at-Risk project. The guidelines in this document are intended to assist the Web-at-Risk's project's curators in developing plans for the collections they will create using the project's Web Archiving Service (WAS). A web collection typically consists of a group of web-sites related by a common subject, theme, or event. Librarians will notice that some familiar concepts and practices from collection planning for print materials easily transfer to collection planning for web-published materials while some new concepts and unfamiliar practices are introduced. To effectively manage collections of web-published materials, it is good practice to either create new plans or modify existing collection plans to address these concepts and practices.
