Drawn from Oxford History Society's "Collectanea". He was one of the three contributors to Collectanea Topographica et Genealogica. Morton continued to write, lecture, and answer inquiries at the Collectanea even after retiring. He left several works, but only the "collectanea" to the Pentateuch have been published. An account of Grocyn by M. Burrows appeared in the Oxford Historical Society's "Collectanea" (1890). These were published in 1815 under the title "Collectanea litteraria". He left a hundred volumes of manuscript collectanea for the completion of his work. In 1751, Blomefield published his Cambridgeshire notes as a single volume entitled "Collectanea Cantabrigiensia". He was one of the three contributors to "Collectanea Topographica et Genealogica". The first edition, titled "Collectanea Adagiorum", was published in Paris in 1500 CE. The barrow then received a mention in George Payne's "Collectanea Cantiana", published in 1893. The "Codex Hamilton", MS 254 in the Staatsbibliothek zu Berlin, was such an epigraphic collectanea. Gaius Julius Solinus' "Collectanea rerum memorabilium" also makes reference to the city. In 1861, Roach Smith published volume five of his work "Collectanea antiqua".
