' Loudon is be-st known by a very rare catalogue of English literature [suiira], vvhich he drew up in 1658 . . , The 

 signature * William London' attached to the dedication has been absurdly explained as that of William Juxon, Bishop of 

 London. Besides the dedication , . , there is an ' Epistle to the most candid and ingenious reader,' and a very spirited 

 and well-written ' Introduction to the Use of Books, or a short Essay upon the Value and Benefits of Learning and 

 Knowledge ' (pp. 49) , , . London's claim to have produced the earliest catalogue of any bibliographical pretensions is 

 fully .iustUied.'— .Sir Sidney Lee.
