[7] It was probably during these years, before Poore held an episcopal office, that he completed Osmund's Institutio, as well as his own works the Ordinale and the Consuetudinarium.

Both the Consuetudinarium and the Ordinale were basically guides to the Sarum Rite, the usual form of liturgy in thirteenth century England.

[7] Poore's brother Herbert died in 1217, and Richard succeeded to his position as Bishop of Salisbury by 27 June.

[12] He owed his move to the see of Salisbury to the papal legate, Cardinal Guala Bicchieri.

In 1223, with the fall from power of Peter des Roches (bishop of Winchester), Ranulph earl of Chester, and Falkes de Bréauté, Poore helped Hubert de Burgh take over the government, along with Stephen Langton and Jocelin of Wells (bishop of Bath and Wells).

Poore petitioned Pope Gregory IX to have the second bishop of Salisbury, Osmund de Sees, canonized, but was unsuccessful.

The quarrel had begun under Richard Marsh, and had led to appeals to the papal curia from the monks.

[20] Also during his time in Salisbury, he promoted the education of boys by endowing some schoolmasters with benefices provided they did not charge for instruction.

His tomb was claimed for both Durham and Salisbury, but most likely he was buried in the church at Tarrant Keyneston which was what he had wished.
