Just today I learned that the Liber Psalmorum, ie., the Latin Psalter, as well as the English/Latin Psalter, are now available at Amazon.
The Book of Psalms in English & Latin is a softcover, 6 X 9. And the Liber Psalmorum (Latin Psalms-English Preface) is a very handy 4.25 X 6.875, softcover. Each is also available as downloads.
You can buy them at either of two places:
1. At my storefront at Lulu.com,
2. And also now at Amazon.com.
My next project will be a traditional English only Psalter, in the Coverdale version. It will be about the same size as the Liber Psalmorum. Then it will be on to other things that are simmering on the back burners.
