SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

Historia Mathematica publishes historical scholarship on mathematics and its development in all cultures and time periods. In particular, the journal encourages informed studies on mathematicians and their work in historical context, on the histories of institutions and organizations supportive of the mathematical endeavor, on historiographical topics in the history of mathematics, and on the interrelations between mathematical ideas, science, and the broader culture.
In addition to research articles, Historia Mathematica also publishes book reviews, abstracts of the current literature in the history of mathematics, notes and sources, and occasionally letters to the editor.
Research Areas Include:
• Interrelations between mathematics and the natural sciences, social sciences, humanities, arts, religion, and education
• Mathematicians and their work in context
• Organizations and institutions
• Pure and applied mathematical developments
• Sociology of mathematics
