Based on what I have read in the forums here, I think that it is possible to share a Calibre library which is on a removable hard drive (ie. disconnect it to use with each computer separately). However, the two computers I am interested in using it on have different versions of Calibre installed as one is much older than the other. If I edit the library in the newer version (eg. change metadata or delete items), will it cause problems when using it on the older version? Or vice versa? The library was originally created using the older version of Calibre, if that makes a difference.
