PIO enables users to search for articles by words or phrases in the titles, by author, and by journal title. It fills an enormous gap in access to scholarly, periodical literature for the humanities and social sciences. PIO now makes it possible to search back volumes of journals with the same ease and convenience as searching the latest issues. Even if their library holds these indexes, searches can be time consuming and incomplete. However, if researchers need to find articles in periodical back volumes, they have to search through dozens, if not hundreds, of printed subject indexes and bibliographies. Over 30% of the content indexed is from non-English scholarly titles.įor more than 200 years, periodicals have been a vital resource for scholars. The scope is international, including journals in English, French, German, Italian, Spanish, and most other Western languages. Complete runs of these titles are indexed, from first issue to 1995 or ceased date. Over 6,000 journals are included, with around one million records from new journals added yearly. Periodicals Index Online (PIO) (formerly, Periodicals Contents Index (PCI)), is the leading multidisciplinary index to the arts, humanities, and the social sciences. This is because Google Scholar indexes web pages not organized collections of article citations, like databases.Three centuries of the arts, humanities, and social sciences indexed coverage, from first issue to 1995 or ceased date, are offered in this newly released database, with access to a growing collection of over 18 million citations. Google Scholar usually provides the highest h-index compared to other sources. A number that is considered low in one field might be considered quite high in another field. You should also keep in mind that what is considered a "good" h-index may differ depending on the scientific discipline. Since databases cover different publications in different ranges of years, the h-index result will therefore vary. This is because each database must calculate the value based on the citations it contains. Keep in mind that different databases will give different values for the h-index. Pure (MD Anderson Faculty and Fellows listed) The following resources will calculate an h-index: The h-index, however, would be much lower, signifying that the scientist's overall body of work was not necessarily as significant. For instance, if a scientist published one paper many years ago that was cited 9,374 times, but has since only published papers that have been cited 2 or 3 times each, a straight citation count for that scientist could make it seem that his or her long-term career work was very significant. Part of the purpose of the h-index is to eliminate outlier publications that might give a skewed picture of a scientist's impact. If the scientist's 18th most cited publication was cited 18 or more times, the h-index would rise to 18. If the scientist's 18th most cited publication was cited only 10 times, the h-index would remain at 17. For instance, an h-index of 17 means that the scientist has published at least 17 papers that have eachbeen cited at least17 times. The h-index is calculated by counting the number of publications for which an author has been cited by other authors at least that same number of times. The h-index is a number intended to represent both the productivity and the impact of a particular scientist or scholar, or a group of scientists or scholars (such as a departmental or research group).
