In response to the steady stream of visitors to Dobbin Mill, Silverberg began a series of artist books where a visitor was invited to collaborate with her on a page of a book, in the spirit of a guest book. Silverberg produced individual papers for each participant. After ten guests complete their signature page, she designs and binds the book and sends each participant a copy.

Here is an example of the first completed Guest Book - of a selection of visitors in 1998:

• Katrin Dieckmann, Germany/NY
• Christine Dixie, Grahamstown, South Africa
• Agnes Eperjesi, Budapest, Hungary
• Leora Farber, Tennessee/ Johannesburg
• Sophie Gruber, Vienna, Austria
• Arimichi Iwasawa, Kyoto, Japan
• Sugar Janos, Budapest
• Linda Sihali, Soweto
• Döce Váradi, Budapest
• Diane Victor, Johannesburg
