Fanon Discontinuity: Many Halo fans like to pretend this book doesn't exist, if they don't flip out in anger at its mention. Most notably, the fan-wiki Halopedia documents all the canon from Glasslands... but isn't above passive-aggressively reinterpreting it in their favor. Just look at this excerpt from the Catherine Halsey article.
Halopedia: Many of those unfamiliar with the internal dynamics of ONI and the SPARTAN-II Programnote have come to interpret Halsey and her work in a highly negative light. [...] Such views often have their basis on information provided by the Office of Naval Intelligence,note which has frequently used highly selective or outright false informationnote to shift the blame for some of ONI's more questionable decisions on Halsey alone.
