Clifford L. B. Hubbard

"Clifford L B Hubbard affectionately known as ‘Doggie’; to his myriad of friends and devotees throughout the world was arguably the greatest canine bibliographer of all time. Up until he died aged 84 years in 2000 he continued to collect books entirely on canine subjects, the bulk of his collection of 24,000 volumes which contains the rarest of books is now in the National Library of Wales in Aberystwyth." https://www.ourdogs.co.uk/News/2003/November2003/News071103/doggie.htm
