There are three services here: content, abstracts, commentary.
Any business model not based on the "content is free" model is
doomed to failure, so you have to get paid for the ongoing service
of providing abstracts and commentary. The writers are paid a
one-time fee for the content, plus a commission on future sales
of commentary on their article. Articles are put into a search
engine that users browse. It brings up the title and one-line
description of each article that hits the search, and has links
to (a) the full content, for free, (b) brief abstracts/summaries
written by the journal's editors or other writers, each of which
has eir own point of view/style, and (c) recently-written
commentary on the article by the journal editors or other writers.
(b) and (c) are constantly updated, and are charged for, but the
customer is buying their novelty, their trust in a writer, their
ability to explain complex work, etc.; They're not buying content
by itself, they're buying the service of making the content easier
to find, organize, and understand.
Another thing you can sell is access/interaction: for $5, ask the
writer a question to which you are promised either a useful
response or your $5 back. Of course, each question and its
answer becomes a new commentary product for you to sell.
It is important that the full-blown content be there--you can't
/only/ sell commentary. It might work, but if the service works,
your custmers will become more expert in the fields they research
(that's what they're paying you for), and will want the gory
details of everything, and will probably change their searching
habits (perhaps they begin by reading reviews by someone who is good
at simplifying things for beginners, then progress into reading
commentary by intermediate-level writers, then finally to reading
critical analysis by other authors in the field.
The hard part will be extricating the minds of authors from chronic
paper-think that infests the publishing world. Convincing them that
giving their material away will make them twice as rich as hording
it, especially if they dabble in reviewing each other.
