I really hope Logos will add 2000 Years of Prayer compiled by Michael Counsell and published by Morehouse Publishing. It appears to be out of print except for the Kindle version. Thankfully used copies are available. There was also a paperback printing by CANTERBURY PRESS NORWICH.
This volume has great devotional and liturgical value and Logos could give it the attention it deserves. Plus, a fully indexed Logos version would be amazing! I'm praying this happens,
Ben
