During the eighteenth century, except for Strype, the archives appear to have been unmolested. Early last century Sir Francis Palgrave made many extracts from this treasury. More recently, M. Auguste Thierry published certain treaties of commerce of the thirteenth to fifteenth centuries, between the citizens of London and the merchants of Amiens. In 1843 M. Jules Delpit spent some time at the Guildhall collecting from copies of documents relating to the connections between France and England. Since then the work of publishing and annotating these papers has gone on with great diligence. A list of the items which comprise the City archives is given by Riley:— “In addition to the early Registers, or Letter-Books, from A to K inclusive (the respective dates of which are given at the conclusion of this volume), the Record-room at Guildhall contains the following compilations:—_Journals_ and _Repertories_ of the Courts of Aldermen and Common Council from A.D. 1417 down to the present time. _Liber de Antiquis Legibus_, a Latin Chronicle of the City transactions from A.D. 1178 to 1274, the only one of the records hitherto published. _Liber Horn_, a miscellaneous collection, date 1311, and compiled probably by its original owner, Andrew Horn. _Liber Custumarum_, a compilation of a similar nature, date about 1320, and put together probably under the supervision of the same Andrew Horn. _Liber Albus._ _Liber Dunthorn_, a compilation in Latin, Anglo-French, and English, prepared between A.D. 1461 and 1490. _Liber Legum_, a collection of laws from A.D. 1342 to 1590. _Liber Ordinationum de Itinere_, compiled _temp._ Edward I.: in addition to which, there are the _Assisa Panis_, commencing in 1284; _Liber Memorandorum_, date 1298, and several other manuscript volumes of inferior note and value. Among the books which are known to have formerly belonged to the Corporation of London, but are now lost, are the following:—_Liber Niger Major_, and _Liber Niger Minor_, both quoted in _Liber Albus_, _Speculum_, _Recordatorium_, possibly identical with the _Liber Regum Antiquorum_, also lost; _Magnus Liber de Chartis et Libertatibus Civitatis_; _Liber Rubeus_, and _Liber de Heretochiis_, both mentioned in the Letter-Books, according to M. Delpit, as formerly in existence. It is not improbable that these volumes may have disappeared on the disastrous occasion when, in the reign of Edward VI., the Lord Protector Somerset borrowed three _cartloads_ of books from the Library at Guildhall, none of which were ever returned.”—Riley’s Introduction to _Liber Albus_.
