Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

The English reader has now, in the first three volumes of this Library, a complete collection of the historical writings of the Fathers, whose permanent value, as sources, is universally acknowledged. Several of them have never before appeared in English. The unavoidable delay in the publication of the third volume has been very annoying to the general editors and publishers, but the subscribers will be amply compensated by the addition of the writings of Rufinus, which were not promised in the prospectus. It is encouraging that this difficult and costly enterprise is beginning to be duly appreciated by competent judges on both sides of the Atlantic.
