Chemical. Search the collection database. Registration numbers The most common type of Museum number begins with the year of acquisition. The database standardises these numbers in the form, for example: 1887,0708.2427 (year: comma: block of four numbers - usually representing a month and day: full-stop and final number). The final number can be of any length and may be followed by another full-stop and a sub-number. In some cases the same number is shared by two or more objects across departments. In some of these cases a prefix has been added before a number (e.g. Oc1946,1027.5). If the number you are entering has come from an old catalogue it could appear in the form 1887-7-8-2427.
In the case of some two-dimensional works from Asia and the Middle East a full stop may need to be inserted into the final number. The second most common type of Museum number takes the form of one or two letters followed by two numbers.
