If you wish to become a DEMHIST member, there are 3 ways to accomplish this:
1) If You are not yet an ICOM member
ICOM has two types of committees: National Committees (by country) and International Committees (by specialty). First, you must join your ICOM National Committee (e.g. ICOM Portugal, ICOM US), you can then select DEMHIST as your main International Committee.
You can find your national committee here http://icom.museum/en/network/committees-directory/
2) If you are an ICOM member but your main International Committee is not DEMHIST
Send the following message to the ICOM Membership service via email@example.com:
I am an ICOM member (membership number:…) and wish to become a voting member of DEMHIST. Please register me with DEMHIST / change my voting choice to DEMHIST.
Strike out as appropriate, and add your name and ICOM number. Do not forget to copy the DEMHIST Secretary - firstname.lastname@example.org
3) If you are an ICOM member, It is also possible to select or change your international committee affiliation through the ICOM member-space on the ICOM website, if you do this, please send an email to the DEMHIST Secretary - email@example.com informing us of the change
