I am quite young but embarked on a rather new challenge for me: writing a book. There aren't so many books on this specific topic in my field: maybe 2 or at most 3 good references, with the first two quite old. The trouble for me is that although there is some clear original stuff in each chapter/section, the main reason for writing the book, the methods (some algorithms and numerical stuff, many equations) are quite standard and all good lecture sets (not too many) draw from these two books.
My book would be clearly better organized than the previous ones. However, the methods are basically the same. I mention that this chapter draws from x and y source, and sometimes that the theoretical part of a certain section is according to z source.
Would citing my sources be enough in terms of not having issues with plagiarism?
