I'm sure many of you have received invitations
to prepare or review papers, or to join Editorial Boards for new
journals that you may not have previously heard of, many of which state
they operate under an open-access model where papers are freely
available on-line once accepted.
There is an ever-increasing list of questionable open-access
publishers and individual journals. Many do not identify their Editors
or members of their Editorial Boards, they may appear to have addresses
in the USA or UK, but are frequently operating out of India, Pakistan
and African countries, and many of these journals have titles similar to
well-respected journals. All manuscripts submitted to such
journals are accepted, with the 'owners' of the journals then requesting
a significant 'publication' payment from the authors of such accepted
papers.
