Dear museum collegue, I wonder if some one could generously provide me with email IDs of Ontario Sci ence Center and the California Museum of Science & Industry. Recently I have tried to send emails to [log in to unmask] for Ontario Sc ience Center and [log in to unmask] for California Museum of Science & I ndustry, but both efforts failed. They might have changed their IDs. If the generous colleague(s) can put on the right numbers for these important museums on the Museum-L, I am sure many other colleagues can derive great bene fit from these postings of information.
