- Identifying Sloane’s books
Because the numbers were commonly written in the corner of a titlepage or flyleaf they have often suffered damage. When a Sloane number is not complete, damaged or otherwise partially illegible, it is entered in this catalogue with an open square bracket, for example, a 145[ . This number will be retrieved as a 145 even though the actual Sloane number might be a 1450, a 1451, etc. 
signifying a purchase date of 1686 and a price of three shillings.
The symbols often appear, as in this case, joined together. This inscription can be transliterated as purchase date 1697 and price two shillings and sixpence.
The picture is confused, however, by the continuing use of the stamp on later acquisitions, and by the use of similar but re-cut stamps as late as 1829. As evidence for Sloane’s ownership the presence of the stamp alone is not conclusive, but highly indicative. Books with the stamp but no other definite evidence of Sloane ownership are probably Sloane’s. For further details of stamps, see P.R.Harris, ‘Identification of printed books acquired by the British Museum, 1753-1836’ in Libraries within the Library, ed. G. Mandelbrote and B. Taylor (British Library, forthcoming 2009)
Manuscript notes or inscriptions often indicate Sloane ownership. The book may have been sent to Sloane, bearing his name or address, or he may have written his name on the book. Quite commonly his books are inscribed “Bibliothecae Sloanianae”, often followed by his number. This note appears particularly on prestigious and attractive items. This is a definite form of identification.
A small number of Sloane’s books bear small paper labels on which are written the Sloane numbers. The typical images below show the number at the top left-hand corner of the cover, and the letter at the bottom. Labels sometimes appear on the titlepage. The presence of this type of label is a definite form of identification of a Sloane book.
- Sloane’s catalogues
Of the three catalogues, the first, Sloane Ms 3995, is a small volume which records Sloane’s purchases from 1685 to 1687, which has not been used as background for this catalogue. The principal catalogues of his printed books are firstly a manuscript catalogue, now in the BL Department of Manuscripts, Sloane Ms 3972C, with an index at Sloane Ms 3972D. Some leaves, mainly recording manuscripts, were removed and bound as Sloane Ms 3972B. Secondly, medical books in Latin are recorded not in the manuscript catalogue, but in an interleaved copy of a bibliography of medical literature, J.A. van der Linden, Lindenius renovatus, Nuremberg, 1686, BL 878.n.8 (Note: this book is fragile and must be consulted on microfilm). The fact that separate and very different catalogues were used means that it is extremely difficult to fully identify Sloane’s books completely from these sources.
The identification of Sloane‘s books has proceeded not from these catalogues but from examination of the books. However, these catalogues have been used on occasion to clarify Sloane numbers and may be referred to in the catalogue record.
