Published posthumously in 1893, Frederick Scrivener's Adversaria Critica Sacra remains a volume of key importance to biblical scholars today, representing Scrivener's remarkable accuracy in his study and collation of manuscripts. During an age when many manuscripts were being newly discovered, and New Testament textual criticism was a rapidly developing field, Scrivener's collations played an important role in highlighting and making available the many different readings in existence. The book presents sixty-three manuscripts containing all or part of the Greek New Testament, including twenty which contain the Gospels in whole or in part, fifteen Lectionaries (Greek Church Lesson-books), five copies of Acts and the Catholic Epistles, and ten which are collations of the earliest printed editions of the Greek New Testament. Scrivener provides an informative general account of each manuscript, and an estimate of their respective critical values.
