I have spent the morning cataloging a couple of shelves of my library here: http://www.librarything.com/catalog.php?view=kmeintjes&shelf=list&sort=title It is about 20% of what I have, in terms of meters of bookshelf space. Comments are welcome - I think this will end up being quite useful for me*. For older books that may not have an ISBN (and even those that do) making the catalog is still quite a manual process, but it sure is better than doing it entirely from scratch! Comments and lookup requests (within reason) are welcome. Keith * I have just discovered I have two pristine copies of Robert Ross' "Cape of Torments". In the future, I can take my catalog with me and avoid this sort of thing.
