The Bodleian Library’s catalogues have a complicated history. New acquisitions are of course catalogued online and appear straight away on the online catalogue, SOLO. However, the collections have been acquired over the centuries and earlier records were made on index cards, in printed volumes and even as handwritten records. Over the years, these earlier records have been converted into online records, but the information is not always as comprehensive as it would be if we acquired the item now and catalogued it to modern standards.
So when we occasionally discover that we have two duplicate records for the same thing, and that it’s been in our collections for over 200 years, this isn’t particularly surprising and can usually be tidied up quickly. A recent case proved more intriguing. We appeared to have 2 separate records for an eighteenth-century map of London. There was one record for 3 copies of the map, and another for a single copy – surely a mistake? The map is a reproduction of one made by John Leake in 1667 after the Great Fire of London. (The need for detailed surveys for reconstruction after the fire led to the making of many maps, and indeed started the map-making career of the famous John Ogilby, who made and published a detailed survey with his step-grandson William Morgan). Leake’s map was reproduced over 50 years later by the engraver George Vertue, reduced in size and with embellishments such as views of notable buildings and streets before the fire.
A dotted line, highlighted in red, shows the extent of the area affected, and a cartouche carries a Latin inscription by George Vertue explaining that the map is a memento of London before the fire, and is dedicated to the Society of Antiquaries of London (who published this version of the map in 1723).
So far this is an interesting map, but there is an associated mystery, for the two versions of it turn out to be not quite the same. In one (presumably earlier) the lower border of the map runs through the River Thames, a little way from the shore. The names of docks, wharves and so on extend into the river. The plate mark (where the edge of the copper printing plate pressed into the paper) can be seen about 0.5 cm below the edge of the map border.
The second copy is different. Although the map is almost identical, and certainly printed from the same plate, it appears that the plate has been trimmed. The lower border of the map has moved up a little and some of the writing has had to be shifted, while the words ‘The River Thames’ overlap the map border. A similar compression has happened at the top of the map. The plate mark is now only just outside the border of the map.
This is extremely unusual. It was common for map plates to be reused and for changes to be made to them; the map might be updated with new information, or the plate sold and the new publisher’s details added, for example. But we have rarely, if ever, seen a case where the plate was cut down to a smaller size. It is uncertain why this was done, but it’s notable that 2 of our 3 copies of the ‘reduced’ version of the map are printed on paper only just large enough to accommodate the map image. It may be that this was a way to produce the map on slightly smaller sheets, either to reduce costs or for ease of binding with other similar items. This was not a case where we needed to de-duplicate the catalogue records, but rather to retain both and explain their complex relationship in more detail.
