The National Library of Wales in Aberystwyth has promoted from within as it names its fourth chief executive in just five years.

The Board of Trustees announced this week the appointment of Pedr ap Llwyd as the next chief executive and librarian.

The library advertised the up-to £92,025-a-year post after incumbent Linda Tomos announced her decision to retire.

Mr ap Llwyd, a native of Penrhyndeudraeth, is currently director of collections and public services and deputy chief executive and librarian at the library and will be the fourth person to lead the famous institution since 2013.

Mr ap Llwyd was previously secretary and head of governance of the organisation.

A governance and human resources practitioner, he graduated in Welsh language and literature from Bangor University where he completed a higher degree in archive administration.

“Being appointed to lead this excellent institution is one of the greatest privileges bestowed on me,” Mr ap Llwyd said.

“I look forward very much to continuing the excellent work which has been achieved under Linda Tomos’s leadership and to implement new and exciting plans which will highlight the richness of our collections and services.

“This is a library for all and reaching new audiences who will benefit from our services will be a priority for me.”

Rhodri Glyn Thomas, president of the National Library of Wales, said: “It’s a pleasure to welcome Pedr ap Llwyd to this key post to build on the excellent work being achieved by Linda Tomos, and to lead the Library in an exciting and challenging time.”

Long-serving Andrew Green retired as chief executive and librarian early in 2013 after filling the role for 14 years. He was succeeded by Aled Gruffydd Jones.

Mr Gruffydd Jones’s tenure was dogged by financial issues which saw jobs cut to balance the books and a row over his management of the library which ultimately led to his resignation.

He stood down in 2015 days after a highly critical report said he had mishandled disciplinary action brought against two of the library’s senior staff members.

An earlier employment tribunal ruled the library had unfairly dismissed Arwel Jones, its director of public services, and Elwyn Williams, who headed its promotion and interpretation section.

Mr Gruffydd Jones’s successor in 2015 was Linda Tomos, who will retire in April next year.

The library has undergone several job-shedding exercises in the past five years in an attempt to balance the books. A major restructuring exercise was carried out, placing dozens of jobs at risk as the library consolidated departments and roles.
