Andrew Green (librarian)

Andrew M. Green MCLIP, FLSW is a former librarian at the National Library of Wales in Aberystwyth, who held the role from 1998 to 2013. His predecessor was J. Lionel Madden. The role has been influential in Wales, since John Ballinger first took up the position in 1909.

Green's career had been in British university libraries including the University College of Wales, Aberystwyth (1973–74), University College Cardiff (1975–89), University of Sheffield (1989–92) and was the Director of Library and Information Services at the University of Wales, Swansea (1992–98).

Though not a native Welsh speaker (having been born and raised in England) Green is fluent in the language. At the 2009 National Eisteddfod, the Gorsedd of Bards honoured him with bestowal of the white bardic robes of a druid. His bardic name is Gwallter bach ("Little Walter").
