In the days before the computer, 'Hyperlinks' were achieved by attaching a piece of string to the document in question and running the string around the office on a system of levers and pulleys. When the document was desired the member of staff would simply pull on the appropriate string until the document arrived in their mitts. The only problem arose when more than one person wished to view the document at any one time. This was overcome in 1924 when Archibald Garrison devised the Compact Waif-Duplicator™, which duplicated the document in crayon on tracing paper. The Waif-Duplicator was operated by a small child in a box.
