A slow fire is a term used in library and information science to describe paper embrittlement resulting from acid decay. The term is taken from the title of Terry Sanders 's 1987 film Slow Fires: On the preservation of the human record.
Books are immersed in a de-acidifying bath, allowing the magnesium oxide to penetrate.

Lecture Notes in Mathematics is a book series in the field of mathematics, including articles related to both research and teaching. It was established in 1964 and was edited by A. Dold, Heidelberg and B. Eckmann, Zürich. Its publisher is Springer Science+Business Media (formerly Springer-Verlag).
Mathematics textbooks are conventionally built up carefully, one chapter at a time, explaining what mathematicians would call the prerequisites before moving to a new topic. For example, you may think you can study Chapter 10 of a book before Chapter 9, but reading a few pages may then show you that you are wrong.
The Class VIII (ages 12–13) book (Punjab Textbook Board) on Islamic Studies reads: "Honesty for non-Muslims is merely a business strategy, while for Muslims it is a matter of faith."
