I finally decided to set up a LibraryThing catalogue of my books. I’ve so far added most of my archaeology books in English, and I must say that it’s far better and easier to work with than expected. The only major annoyance that I’ve so far encountered is that it is sometimes very difficult and often impossible to find books published in German, French and Italian – not to speak of Danish. Of course, this means that my catalogue will never be complete, and that slightly annoys me.
Update: I see that LibraryThing now has added the collections of the Danish Royal Library and several other European libraries. Now they just need to sort out full support of the Danish letters ø, æ and å!
