I ran my workshop about the invisible web at Irandoc and in my opinion it was very successful. Twenty participants took part in the workshop during two days and they showed their enthusiasm about the topic by their active participation in the discussions and practices. Most of them were academic librarians and mangers of libraries from different parts of Iran. It was very encouraging for me that they participated in the discussion so enthusiastically. I will run the same workshop at Irandoc for another group in the next week.
