As I have previously posted, Mad Scientist Journal is an ezine that publishes new fiction weekly on its website--that you can read for free. They also amalgamate their stories into quarterly anthologies and add some exclusive content to give more bang for your 99-cent download.
Initially published through smashwords in a number of formats, these anthologies are now available in kindle editions on Amazon. Links to all four, currently available, anthologies are on the MSJ website. My own contribution in the form of a classified ad, Experienced Osteo-transplant Specialist Seeks Work, from Dr. Coccymandible, can be found in the Autumn 2012 Anthology.
Feel free to write a review of one (or all) of these anthologies on Amazon, your own blog, or elsewhere. Help MSJ expand its audience.
An upcoming anthology (Spring 2013, I expect) will also include my short story, Mabel's Mission, which was published by MSJ on Apr 1st.
