The National Heritage Board IMD'07 website has more details on the various events across 24 museums, from 18th to 27th May. Basically, through IMD'07, NHB hopes to make heritage and culture more accessible to everybody:
Something new I learned from the IMD'07 website -- Singapore Collections Online:
The search feature only covers objects from the Asian Civilisation Museum, the National Museum of Singapore, and the Singapore Art Musem -- though the homepage of SGcool.sg says, "From time to time, you can view and appreciate the digital collections of other non-NHB museums in SGCOOL. Over time, we will also be releasing more artefact and artwork images from our own collections periodically."
Walter (aka Cool Insider), who works for NHB, shares more on the various activities for IMD'07.
They even have a twitter page for IMD'07! I believe most Singaporeans aren't aware of Twitter.com, so efforts to publicise events via Twitter would be limited. At least I'm speaking for myself -- I have a Twitter account but am an infrequent reader/ user.
Btw, I used to think there were only four or five museums in Singapore. Did you know there are at 43 museums right now? See the Museum Roundtable website.
