Many moon s ago had a stack of these publications.  Unfortunately lost them all.  Been looking at a few that I interested in purchasing.  Big question, " How useful are they.  Considering in some the scope is very narrow and the age they cover.  My interest late 40's - early 50's.  Know there are numerous publications that cover this time range.  Some of the "T.S." seem to overlap and has mentioned above.  Don't know if I have an interest in boiler design and terminals of the 1890's.
