I’m a little late but I log mine on Library thing. I can add ebooks and physical books manually or by scanning the 978- barcode, can sort into series, manually add collections (I do manga, novels, light novels, non fiction and children’s books) and can add tags and language (for if you have books in more than one language, eg I have Spanish, English and Japanese books).
I like that I can search for books on there to see if I have it, can also see at a glance how many I have from a series or the order they should be in (detective Galileo series) and can find them via the cover too.
It’s free and has a free app (both android and iOS) but you need to manually add books though the website and the barcode scanner is only on phones/ tablets.
I wanted my book titles in Japanese and this was one of the few where I could type Japanese in the fields. There’s also a lot of customization options and a handy how to guide for almost everything on the site. You can also add random stuff but it may not populate anything other than the info you put in - eg if you are adding web-novels and such.
I do use natively for tracking books read etc but I needed something I could check quickly and when out and about to see if I had certain books. Some of them aren’t on natively because there’s no amazon listing for it but I can still add it to library thing without issues.
