Hello Violaine,
In principle there's nothing wrong with using a Frame file in several books. If you are doing this on one machine there should be no problem. If, however, the common file is to be found on a server and several writers will need to use it, then you may need help from your sysadmin people to ensure that all users map the server drive in the same way. This because of the way that Frame uses relative or absolute pathnames. To ensure that a given document can be updated on any machine you need to ensure that the path name used to find the file is consistent across all platforms. You should also work out how any cross references will work. With shared files I would use spot references where you decide what the marker id is to be. Better still, avoid cross references between shared files and non-shared files. Another thing to watch out for is template origins. If you use different templates you might have issues of color definitions and other bits and pieces that make updating book files a nuisance.

Bottom line is - no problem, it's done all the time when the decision is well thought out and documented.

If you don't need an entire file in a book but could use say a referenced fragment of information you could consider text insets. For this approach there's another set of design considerations.
Cheers
Ian
