Be aware that many items are not scholarly journals. The University of Pennsylvania Libraries offer access by title or broad subject area to a mixed collection of scholarly journals and ordinary magazines. Although there is only access by title, the University of Houston Libraries has done a great job of providing a long list of Web-based scholarly journals that do not require registration or payment of a fee. There also is a link to a list of recent additions. This list which specializes in the social sciences forms part of the World-Wide Web Virtual Library.
