Have just uploaded my book spreadsheet to Library Thing.  Good news? 937 of my books have ISBN numbers so have been able to batch upload them.  Bad news? Need to manually input over 700 more...

If you want to see the collection so far, it's here.

Ok - so far the following sections have been entered into the spreadsheet (including ISBNs where relevant - i.e. anything past 1972ish), sorted and put up on shelves:

• Art & Architecture
• Biography
• Business
• Fictional Prose (non-genre)
• Poetry, Drama & Criticism
