Today, pocket psalters are still in use. Pocket psalters (of the 1650 Scottish Metrical Psalter version) from the Trinitarian Bible Society have been available for some time. Currently, the best price and source to obtain them seems to Reformation Heritage Books. We use them in our family, and my children, in particular, enjoy them very much. They provide a handy format for singing the psalms wherever one may be and that is a very good thing.
Scottish Metrical Psalter - Psalm 147.1:
1 Praise ye the Lord; for it is good
praise to our God to sing:
For it is pleasant, and to praise
it is a comely thing.
