For example one of the most popular introductions to history for undergraduates is John Tosh. If you can access a copy of The Pursuit of History he explains the difference between history and science in a chapter called "The Limits of Historical Knowledge" (Page 185: pages differ in the 6 different editions of the book).
Tosh explains: "although history and the natural sciences may converge in some of their fundamental methodological assumptions, important differences remain." He alaborates and explains many differences in the pages that follow, including greater role for imagination, empathy, impossibility of consensus, uniqueness of hisrical events, and much more.
"The rigid segregation of fact and value demanded by the positivists is unworkable in history. In this sense, historical knowledge is not, and cannot be, 'objective' (that is, empirically derived in its entirety from the object of the enquiry). This does not mean, as sceptics might suppose, that it is therefore arbitrary or illusory. But it does follow that the assumptions and attitudes of historians themselves have to be carefully assessed before we can come to any conclusion about the real status of historical knowledge."
