Although the Library does not have access to Web of Science and its Journal Impact Factor ratings, we do have SCOPUS. SCOPUS provides access to the SJR (SCImago Journal Rank), a similar rank/impact factor. To find a journal's SJR, go to SCOPUS and choose "Analytics" from the menu at the top of the screen, then follow directions for searching by journal title or subject area.
Many of the article citations you find by searching the article databases will link directly to the fulltext of the articles. Sometimes, however, you may find a citation somewhere such as another article's reference list, or someone may recommend a particular journal title. In that case, you will have to check to see if the Library either has access to the fulltext of the journal online or a print or microform copy in the Library.
To see if a particular journal is in the Libraries' collection, or to browse journal titles by discipline, use Our Journal List. If you have a citation and want to see if the book or article is available in the USA Libraries, use Citation Linker.
This is a sampling of journals, available fulltext through the Library, that may be relevant for your research. It is not an exhaustive list and there are many others which may be found by searching the Article Databases.
