There's another thread recommending him in the generic Suggestions forum, but I have a feeling this will get more attention here:
William Perkins (1558–1602) was an influential Puritan theologian. "Perkins was a prolific author who penned over forty works, many of which were published posthumously. In addition to writing, he also served as a fellow at Christ's College and as a lecturer at St Andrew's Church in Cambridge. He was a firm proponent of Reformed theology, particularly the supralapsarian theology of Theodore Beza and John Calvin. In addition, he was a staunch defender of Protestant ideals, specifically the five solae with a particular emphasis on solus Christus and sola Scriptura." (Wikipedia)

Many of his works are available in Kindle format. These at the very least should be made available in a William Perkins bundle in CP.
