Hosted by the American Mathematical Society, the aim of AMS Digital Mathematics Registry "is to provide centralized access to collections of digitized publications in the mathematical sciences" and related areas like computer science. This includes both journals and journal-like book series. The resource list can be sorted by title or source (publisher). For every title listed, there's an indication whether it is freely accessible, a subscription is needed, or it is a combination of both.
The Classic Computer Magazine Archive contains the table of contents and full text of computer magazines from the mid-1970s through the mid-1990s. Magazines like Creative Computing, Compute!, Antic Magazine, and Start Magazine are covered. Full text is not available for all of the contents. The site is browsable and searchable.
Arranged alphabetically by title, this is a directory of selected computer science journals. It provides access to tables of contents and the publisher's Web pages for the journal. There are also links to other journal directories.
Compiled by Lund University Libraries, it lists free, full text scholarly journals. Each journal entry contains ISSN, subject, publisher, language, keywords, start year, and a link to the journal.
From an article in Issues in Science and Technology Librarianship, it covers free scholarly computing and IT journals. A description of the journal and its URL are furnished.
