Of all the librarian jobs it has to be my least favorite.  Boring, tedious, time consuming.  And easily put off 'till later.  But today I buckled down and it's half done.  I'm going through the list of authors and comparing them with the list of books in the library by categories.  Finding lots of mistakes.  When this job is finally done we will have an accurate record of each book we have listed by authors.  There are times when someone asks us if we have any books by this or that author.  It's a quick and easy reference.  The tedium continues, but one day (soon?) it will be done.  And then I can move on to more interesting tasks.
