Yeah, one of the documents I regularly refer to is 1600 pages on its own. It refers to dozens of other documents that are 1000+ pages each. That's just the hardware though. The languages running on it each have standards docs, which are further hundreds to thousands of pages of material I regularly refer to. Those languages are used to implement software standards, which might be thousands of pages per volume, and have dozens of volumes.
It doesn't matter how fast you read, you're not going to be able to read or retain all of that info.
Also reading something cover by cover is not enough to retain the information. Not even close.
