It wouldn't be that large of an effort for the writers to add a 'suggested reading' list at the end of a book. It was included in 5e PHB.
A lot of RPG books do, and it is fine. My point was, I think it is a mistake to look to RPGs books for knowledge about the real world. These are always going to be games first, usually written by non-experts, who are not typically interested in producing something that is 100% authentic to a given culture, historical period, etc. Books that are accurate and authentic can be made. But I don't think the barrier to entry should be that people must have expertise in a given area, must strive for accuracy, and must always put history ahead of fun. I say this as someone who was a history major. I love history. And for a long time, I was the kind of person who was a nightmare to watch movies with if they were set in the past, because I couldn't enjoy people just having fun with history, or deviating from it. It took me a long time to understand that sometimes, people want to have the freedom to play with this stuff, that it doesn't always have to be accurate or teach people something.
