sourcing question I ve been contacted by the unit historian for 4th Supply Battalion who has given me some information and an image to use for that article However it s not published anywhere but in the unit s records which are not generally accessable to anyone not at the unit s headquarters How would I be able to source this information in order to use it in the article Would I be able to forward the email to OTRS and cite the ticket as a source Or perhaps simply just cite unit historian It would be a shame to be unable to use this history Thanks in advance wordsdeeds
