Ebook in the context of "Self-published"

An e-reader, also called an e reader or e device, is a mobile electronic device that is designed primarily for the purpose of reading digital e-books and periodicals.

Any device that can display text on a screen may act as an e-reader; however, specialized e-reader devices may optimize portability, readability, and battery life for this purpose. Their main advantage over printed books is portability: an e-reader is capable of storing thousands of books while weighing less than a single one. Another advantage is the convenience provided by add-on features.

Brill Academic Publishers (Dutch: Koninklijke Brill NV) is a Dutch international academic publisher of books, academic journals, and databases founded in 1683, making it one of the oldest publishing houses in the Netherlands. Founded in the South Holland city of Leiden, it maintains its headquarters there, while also operating offices in Boston, Paderborn, Vienna, Singapore, and Beijing. Since 1896, Brill has been a public limited company (Dutch: naamloze vennootschap).

Brill is especially known for its work in subject areas such as Oriental studies, classics, religious studies, Jewish studies, Islamic studies, Asian studies, international law, and human rights. The publisher offers traditional print books, academic journals, primary source materials online, and publications on microform. In recent decades, Brill has expanded to digital publishing with ebooks and online resources including databases and specialty collections varying by discipline.

Elsevier (/ˈɛlsəvɪər/ EL-sə-veer) is a Dutch academic publishing company specializing in scientific, technical, and medical content. Its products include journals such as The Lancet, Cell, the ScienceDirect collection of electronic journals, Trends, the Current Opinion series, the online citation database Scopus, the SciVal tool for measuring research performance, the ClinicalKey search engine for clinicians, and the ClinicalPath evidence-based cancer care service. Elsevier's products and services include digital tools for data management, instruction, research analytics, and assessment. Elsevier is part of the RELX Group, known until 2015 as Reed Elsevier, a publicly traded company. According to RELX reports, in 2022 Elsevier published more than 600,000 articles annually in over 2,800 journals. As of 2018, its archives contained over 17 million documents and 40,000 e-books, with over one billion annual downloads.

Researchers have criticized Elsevier for its high profit margins and copyright practices. The company had a reported profit before tax of £2.295 billion with an adjusted operating margin of 33.1% in 2023. Much of the research that Elsevier publishes is publicly funded; its high costs have led to accusations of rent-seeking, boycotts against the company, and the rise of alternate avenues for academic publication and access, such as preprint servers and shadow libraries.
