I have to say it's very hard for me to follow all this.

For most standard collections such as std::vector<T> the serialization library takes care of the version of T. There are only a few exceptions to shis - such as vectorstd::string etc. So everything should "just work"

Robert, Thanks for replying and apologies the explanation wasn't good. I think the solution is to introduce into the MFC Doc class a member variable m_Version and load either std::vector or std::vector< shared_ptr<T> > as appropriate. Trying to read one line and determine the item_version is probably silly. This issue is closely related to my other post today ([Boost-users][serialization] Memory leaks even with shared_ptrs) and I'd be grateful if you were able to give that a look. And a million thanks for the library - it really is an incredibly useful tool. Colin
