A Guide to British Library Book Stamps
Did you know that ownership stamps are applied to items accepted into our collections?
Ownership marking is the application of the official British Library ownership stamp. The ownership stamp is used for security purposes and in tracing the provenance of the collections. Examination of the book itself is quite often the best place to start when trying to establish the history of an antiquarian book, and library stamps (acquisition stamps and book stamps) might indicate how and when it was acquired. Ownership of an item was routinely shown by the British Museum, and subsequently the British Library, by using inked stamps. These stamps give a fairly precise date of receipt for the volume leading to entries in acquisitions registers or invoices. A series of stamps was compiled by René Payne in 2007 from which many of the examples in this post have been taken.
Our Library stamps are generally divided into four types according to when they were in use ranging from 1753 up to the present day.
TYPE 1: 1753–1836
From 1753 to around 1836 stamps containing the words MVSEVM BRITANNICVM or MUSEUM BRITANNICUM were in use. The shape and arrangement of the stamp varied over the years and sometimes contained the initials of the previous owner.
TYPE 2: 1837–1929
Type 2 stamps covered the period 1837-1929 and were oval in shape. They contained the royal arms flanked by a lion and unicorn beside the words BRITISH MUSEUM. Between 1837 and 1849 stamps were annotated with a pencil to indicate the exact date of entry in the acquisitions records. They occur in the shape of a diamond giving the date of acquisition and a reference line in the Acquisitions Register. In the example shown below from the Help for Researchers webpage, moving clockwise from the left the numbers represent the month of acquisition (10 = October), the year of acquisition (44 = 1844), the day of acquisition (18 = 18th), and the entry line in the Acquisitions Register for that day (line 144).
Figure 4: Oval stamps containing the royal arms flanked by a lion and unicorn with the words BRITISH MUSEUM; used 1837-1929. An abbreviated date of acquisition may be added, either with another inked stamp or in pencil. Note the variation in design. After 1929, the stamp was changed to Figure 5 (left)
TYPE 3: 1929–1973
Type 3 stamps were used from 1929 to 1973. They consist of round stamps containing the royal arms but no lion or unicorn, and the words BRITISH MUSEUM. Earlier stamps included an abbreviated date of acquisition e.g. in Figure 5 (left) the date is 15 February 1944.
TYPE 4: 1973–present day
Type 4 stamps reflect the time when items were stamped with the words BRITISH LIBRARY rather than BRITISH MUSEUM - a key turning point in the History of the British Library. The British Library Act was passed by Parliament in 1972 which brought the Library into operation from 1 July 1973.
These round stamps have been applied to early printed books acquired since 1973.
The stamp in Figure 11 shows the initials OIOC (Oriental and India Office Collections) which now reside within the Library's Asia, Pacific and Africa Collections.

These items were treated as part of the British Library collection. Right: Library stamp from previous Oriental and India Office Collections. Use of this stamp ceased on 1 September 2005
Significance of the ink colour
Different colour ink was used for library stamps depending on the purpose. All inks have been tested to ensure they comply with conservation standards.
- Blue ink represents legal copyright deposit material of British, Irish or colonial origin including material from the Old Royal Library
- Red ink typically indicates a purchased item, but a square red stamp may indicate that a book was donated as part of the Edwards Bequest
- Black ink was used on a wide range of early acquisitions, including books from the library of Sir Hans Sloane; on purchases made in 1781–1798 and 1804-1813; and on copyright deposit materials received 1813–1816. It was re-introduced for much of the 20th century to indicate materials acquired through international exchange. Black ink was discontinued on 1 September 2005
- Green ink represents a donation made since 1944, or an exchange item
- Yellow/orange ink represents donations made between 1768–1944
- Brown ink represents a donation made before 1768
While library stamps are a useful aid in determining the history of a collection item, it has been noted that many items were stamped much later than their acquisition date and mistakes are known to have occurred. Library stamps should provide just one piece of a greater body of evidence for determining both the circumstance and date of acquisition. Clues may also be found on bindings, bookplates or inscriptions.
Ownership marking is carried out at St Pancras and Boston Spa in secure areas with restricted access. Our colleagues in the Operations Division are responsible for stamping any new material that comes into the library. A new system is being introduced very soon which we will cover in a future post. Thanks to Graeme Bentley, Goods Inward/Finishing Team Manager, for input on this topic.
