Day and Seres specialized in religious works, such as those by Robert Crowley, which were largely related to theological controversies of the time.
Seres afterwards joined partnership for a time with the printer and translator Anthony Scoloker, and in 1553 received letters patent for the printing of psalters, primers and prayer-books.
[2][3] However, he lost this privilege after the accession of Queen Mary to the throne in July 1553, when the entire religious climate of the country changed.
[4][5] In his old age he assigned his business for a yearly rental to Henry Denham who became a member of the Stationers' Company in 1560.
Seres' important work includes a 1549 edition of John Rogers' Matthew Bible, which was first printed in 1537 by Richard Grafton and Jacobus van Meteren as a mixture of the translations by William Tyndale and Miles Coverdale.
