One of these is the IOStreams library.
Most books try to cover the relevant material in a single chapter.
It is quite inadequate for serious class design. Almost certainly you will be providing io facilities for your classes. To do so properly requires some understanding of the whole process - just knowing how to write a high level inserter or extractor is just not enough. In this book Steve Teal concentrates on explaining the IOStreams library, how it works and how you can add your own functionality. The book would be useful simply for its clear and careful documentation of the library as delivered and I suspect that many 'experts' will be surprised to discover how much they did not know.
