Keep your search simple, this tool searches for all of your search words in the titles and descriptions of documents.
You can enclose search phrases within "double quotes" to find phrases instead of individual words.
The format option allows you to select or sort by digital or non-digitised records.
If you do not find what you are looking for, try searching for alternatives such as abbreviations (e.g. NHNN) or try searching the UCL Archives catalogue.
