I enjoyed reading Expert C Programming: Deep C Secrets by Peter van der Linden after reading that in the early 90s. Also the C standard from the time and the attached 'Rationale' document https://nvlpubs.nist.gov/nistpubs/Legacy/FIPS/fipspub160.pdf (The rationale is 234 pages in). Also this 1995 book version of the comp.lang.c FAQ https://c-faq.com/book/ and https://c-faq.com/
