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.

Paleopathology is the study and application of methods and techniques for investigating diseases and related conditions from skeletal and soft tissue remains. The International Journal of Paleopathology (IJPP) will publish original and significant articles on human and animal (including hominids) disease, based upon the study of physical remains, including osseous, dental, and preserved soft tissues at a range of methodological levels, from direct observation to molecular, chemical, histological and radiographic analysis. Discussion of ways in which these methods can be applied to the reconstruction of health, disease and life histories in the past is central to the discipline, so the journal would also encourage papers covering interpretive and theoretical issues, and those that place the study of disease at the centre of a bioarchaeological or biocultural approach. Papers dealing with historical evidence relating to disease in the past (rather than history of medicine) will also be published. The journal will also accept significant studies that applied previously developed techniques to new materials, setting the research in the context of current debates on past human and animal health.
Types of paper:
• Research Articles: A full-length, original scholarly article, for example a contextually grounded study of disease one or more ancient communities. Both historical and prehistoric perspectives are appropriate for publication in IJPP. Research articles will usually contain the following sections: Introduction, Materials and Methods, Results, Discussion, and Conclusions. Article submissions should not normally exceed 6000 words excluding tables and citations.
• Case Study: Case studies of special significance are suitable for publication in IJPP. These must be justified in terms of disease, temporal, and/or locational uniqueness. As a rule, case studies are normally less lengthy than research reports and should not exceed 3000 words, excluding tables and citations.
• Technical Note: Normally shorter than research reports (and not to exceed 1500 words excluding tables and citations), technical notes describe innovative methodologies or validation techniques.
• Brief Communication: No longer than a published page (1500 words maximum, excluding tables and citations), brief communications report the presence of a condition not sufficiently unique to merit a longer treatment (case study). Brief communications register data that may be useful for other researchers wishing to initiate comparative analyses.
• Review: Reviews of periodicals, books or other media related to paleopathology. Book reviews will normally be solicited by the IJPP Review Editor. Individual volumes of special interest to the readership of the IJPP are appropriate, as are volumes in related fields. Cluster reviews of recent publications that place them in historical and disciplinary contexts are also encouraged. Authors who wish to volunteer individual or cluster reviews should consult with the Review Editor concerning the suitability of material and length of the contribution.
• Invited Commentary: Commentaries invited by the Editor-in-Chief.
