This message is for TNAUK users of the BC: I believe that the fault I mentioned earlier today, that Section names are doubly reported, has nothing to do with the new BookCourier software, so apologies are due to Springer Design. The fault only occurs in files which contain both sections and sub-sections, when the section does not have a sub-section, the section is repeated. If the file does not contain sub-sections, navigation is correct, as it is for the radio & TV guides. Once again, my apologies to Springer Design - the fault noted above will be corrected in future issues of the TNAUK filter. Regards, Neil.
