This journal article is old but it has good lists. I had a copy of the entire article but I can't find it.

Locked in conversation: the college library collection and the pluralist society. (Special Issue: Collection Assessment and Acquisitions Budgets) Robert L. Houbeck Jr..
Abstract: Libraries should ensure that their collection of journals provide users with a balanced presentation of political views. In this respect, a study was conducted to determine whether academic libraries have balanced resources collections. Two lists of journals were prepared to serve as basis in judging whether a collection is liberal or conservative. One list contains journals that express rightist political views while the other presents leftist opinions. Findings showed that libraries generally have both liberal and conservative journals of opinion in their collections. However, it has been found that a big number of the new conservative journals are not indexed.

There used to be a wonderful published source, Mediaguide : a critical review of the media, edited by Jude Wanniski and published by Polyconomics.  It included not only evaluations of journals, but also of journalists, columnists, newspapers, broadcast media, commentators, etc.  Unfortunately, the last edition published was in 1992.  I still miss having a current edition.

Hello, Julia -
        Funny you should mention that.........  A long time ago (i.e., back in the nineteen seventies) our periodical librarian devised such a list, mostly for her own and her assistant's use although she did share it with me and maybe some of the other librarians then on Reference duty.  I probably have a copy yet, although 'twould be much outdated. Nevertheless your inquiry brings back some happy memories.

Hello.

Does anyone know of or has anyone created a list of policy oriented
journals subdivided by political affiliation? I know that the reference
book Magazines for Libraries annotates journals and describes biases
here, but I wondered if anyone on this listserv has created a public
policy research guide that instead of dividing periodicals by scholarly,
popular, and trade, divided by political slant, left-wing, right-wing,
etc...

Just curious.
