Some of the bibliographies in Oxford Bibliographies Online will include a list of recommended journals. Under "Find this Resource" is the Get it at UC link. Follow that link into UC Library Search and you will be provided with information about our print and/or electronic holdings for that journal. If no results are returned, the Library does not subscribe to the journal.
Many of the article databases provide a list of the publications that are indexed in the database. Not all of these are the same, but often you are given the option to search within the list of publications.
Use a broad topic when searching for journals. In this database, for example, you will find journals related to social media, but a search on TikTok won't be successful. Remember, in this search you are trying to locate Journals on a subject, not specific articles.
You can try different approaches for locating journals related to your research in UC Library Search.
Using the journal search, type in a broad term, like "social media".
Or search for keywords in the basic search, like "social media" AND marketing. On the left is a series of filters. Select the Journals filter under Resource Type.
