How do I maximize the retention of new materials?

Hey all, A lot of people read books one at a time, as for me, I have a number of trivia books I enjoy reading including some educational texts that provide informative topics ranging from science, art, literature, etc. I like to learn a lot from a variety of different sources. My question is that because I jump from one interesting topic to the next is it possible that I am being counter-productive? Is the onset of new knowledge going to offset my former knowledge? I feel like I am retaining the information I have learned thus far, but I tend to analyse my process too much and would like to know what your opinions are on this. Am I not going to retain as much because I am jumping from one topic to the next
