What is 'weighting'?

From postings by boekerij and mangaroo:

"Weighted" sorts on an algorithm that privileges two factors: the obscurity of the books you have in common and the percentage of shared books in the user's library. The numbers in parentheses (1/2) are the number of books you share with the user (1) followed by the total number of books in that user's LT catalog (2).
Thingamabrarians owning some thousands books and sharing some dozens of them with yours out of those of which Thingamabrarians are sharing thousands of copies - e.g. J K Rowling (Harry Potter) and Stephen King - might be less close to your proper interests than other Thingamabrarians sharing but a handful of books with yours if the latter are more obscure if not rare books and that all the wile they are a significant part of their (smaller) collection.

Thus, while most probably most top 50 libraries will contain a handfull of books by LT's top 20 authors--and share them with lots of others Thingamabrarians, the raw number in this matter wouldn't tell you that much about common personal interests, would it--apart of course from (common) huge taste for books. You might share dozens of (rather popular) books with most of those.

On the other hand, some smaller library, all the while that it might be countaining no more than say 200 books, but is sharing e.g. 5% of them (10 books only, that is) with yours might be a closer match to your very proper taste for books, the more when most of those 10 books only are rather obscure books, even some of them shared between both of you and none other.

Raw numbers just tell how many books both of you are sharing. Weighted numbers might tell you more about common specific taste.

Thanks to lilithcat & WholeHouseLibrary:

If you click on the little printer icon at the top of the page in the 'Your library' tab, you get a printable view. You can do this in any of the various catalogue styles.

Or you can download a copy of your whole library in a file that you can open in a spreadsheet and print from there. The Export tools are near the top of the center column on the 'Tools' page.
