"I feel it is my duty to warn others...that they approach the oberserving of variable stars with the utmost caution. It is easy to become an addict, and as usual, the longer the indulgence is continued the more difficult it becomes to make a clean break and go back to a normal life."

Digitization of AAVSO data published in the Harvard Annals

In the 1980s, the AAVSO began a monumental project to completely digitize the paper and punchcard records of the AAVSO.  This project, undertaken just as computers became more common and easy to use, foreshadowed the rapid advancement in networking technology that led directly to the world wide web, and to the AAVSO website.  As a result of the work the AAVSO did, we are now able to serve our archive of over 18 million observations to the entire world via our website, providing decades worth of variable star observations for thousands of different variable stars to researchers world-wide.
