To search on author name, select the 'Author Name' query type and enter the required surname in the text/numeric 'Query' box. Optionally authors' initials may also be specified, but each must be followed by a full-stop with no spaces between initials or between initials and surname, e.g. 'F.H.Allen'. When initials are provided, all must match exactly, e.g. 'F.H.Allen' would not match 'F.Allen'.
When searching against author names, the query 'Allen' will not match names like 'Allenby' and 'Allenford'. The author name search will only return exact word matches.
