I found this today while looking for the table of contents of a book. This looks like a really useful resource.

This allows you to search the books by keyword or by trick type. Comments have been entered for some effects (IE: Variant of Spellbound, uses shell) so searches can be quite accurate.

For example here : http://archive.denisbehr.de/archive/rou ... 13,46,76,3 we are seeing the contents of Props > Coin > Effect Themes > Transformation > Miscellaneous

So not only is this handy for listing books you have, but it also enables you to see where other effects are published that may be similar. It's not 100% as some of the category's are a little broad, but it's still really handy.
