Hello everyone.

I'm reading this forum since 2014 and using Calibre ( thanks Kovid, saved my life!)

I'm bothering you since I have a problem and, even if I tried, I didn't succeed...
(Please pardon me if the section is wrong..)

First: Till now, my shelf name is based on Series'name and, if this is absent, author name.

( that is: I want all the books in a serie in the same shelf, otherwise grouped by author)

Recently I introduced Tags, since I'm started using Calibre to manage pdf manuals (Arduino, Electronics....)

Hence, when creating the Shelf name I need:
1) Shelf name is given by Series name and, if absent, Author name. ( already done!)
2) if Tag is not empty, prefix the shelf column with the Tags value, or better, a given string.
( Given I keep the manuals on the top of the list, I'd like to have:
__ Arduino books
__ Electronics books
__ Other manuals..
then the other books, listed normally.

Thanks for your patience....
Regards.
