As a member of the BTS since 1999, the THS since 2000, and hopefully the ITHS, I haven't the budget to join other organisations. I find the ADB and Commutator so far to be good magazines, always stuffed with information; and I hope the same will go for the ITHS's periodical.
I did wonder why John Eaton, Charles Haas, and others were not still in the THS; Walter Lord mentions them as top officers of that society in his 1986 book. It seems strange that they left, or were told to. Was this why Titanic International was set up in 1990?
Speaking personally, I've found the THS to be a grand organisation, and I hope to continue as a member for years to come.
Best regards,
Mark.
