"Scalar is a free, open source authoring and publishing platform that’s designed to make it easy for authors to write long-form, born-digital scholarship online". Scalar is designed to accommodate "small to moderate amounts of structured content" that "need a lightweight platform that encourages improvisation with your data model". Combining standardization with flexible structure, Scalar is a web authoring tool that integrates and balances a variety of media sources. Scalar is ideal for formatting and publishing "essay- and book-length works in ways that take advantage of the unique capabilities of digital writing, including nested, recursive, and non-linear formats". Scalar supports collaborative authorship and reader responses. Scalar is a project of the Alliance for Networking Visual Culture (ANVC).
