The database "Toxfile" is being created as a subset of the database "Medline", so the Medline journal list would cover all the sources of Toxline. The current list of journals covered by Medline can be accessed through the homepage of the content provider National Library of Medicine (NLM) at
On that page, one can click on the link "List of Journals Indexed for MEDLINE" to obtain the complete list of sources. The list will contain more journals than Toxfile offers, but the provider NLM does not publish a separate source list for Toxfile only.
