Re: OA strategies

Ann,

I hope I've understood your question correctly about open 
backfiles.

There are 261 journals at HighWire where a recent or extended 
backfile is available for free as I think you describe below. For 
these journals, the current content would be subscription-based, 
and the recent back content (e.g., a year or more old) is open. 
(Other sites are completely open, and others have free trial 
periods running.)

For 152 of these 261 journals -- the far-back content (e.g., 
scanned issues from 1995 and earlier) is open; and for the 
remaining 99 journals -- they require an "archive" 
subscription.

So, for example, "Journal A" may have its most recent year 
subscription based e.g, April 2009-April 2010, its content from 
January 1995-March 2010 may be open, and its content from volume 
1 through 1994 may require an archive subscription.

While for "Journal B", its most recent year might be subscription 
based (e.g., April 2009-April 2010), and its content from volume 
1 through March 2009 might be open.

These rules vary by journal (HighWire does not set these 
policies, the journals do).  The rules are captured in a table 
that is used by the providers of OpenURL resolvers 
http://highwire.stanford.edu/librarians/AtoZList.xls and in 
visual form http://highwire.stanford.edu/lists/freeart.dtl
