I have them. I have studied small parts of some of them. I have been delving into them over 30 years.
For day to day programming, I do not need or use the detail in those books.
At various times in the past, I have delved into library writing, and then they were very helpful, mostly in understanding issues and problems that I had not thought about. But I think time has moved on. Hardly anyone needs the details in those books, and in many cases, some classes of problems are well solved.
Looking back, I am glad that I studied some parts. But today I would not recommend them. Unless you really wanted to look back at history.
