       Ask HN: How do I easily catalog a couple thousand physical books?
        
       I own a couple thousand books. I'd like to catalog them all. I have
       a child who is a broke college student, so I was thinking of paying
       them to do it over break.  What's the most efficient way to do this
       from an INTAKE standpoint? I need to get all the ISBNs into a
       database of some kind.  (The only other info I need is whether or
       not it's a hardcover or software -- that's something only the
       physical copy can tell me, everything else I should be able to get
       from the ISBN.)  I don't want my daughter to have to find and key
       all the ISBNs in. Can they be scanned in some way? Is the ISBN in
       the UPC code? Could I buy a cheap bar code scanner and just have
       her scan away?

       | I'll defer to what @Jtsummers said about getting your data out of
       | their database though, as I have not tried that part myself
       | (yet).

         | If you're logged in, at the top is an export option which will
         | generate a CSV file. It includes the ISBN if present and a lot
         | of other columns of data that may be useful.
         | 
         | I don't think that's how I did it when I pulled the data out
         | years ago, but it works and involves no 3rd parties so that's
         | nice.

       | Apps like QRBot [1] have the ability to scan ISBNs (and barcodes
       | generally), and have a "history" feature that keeps track of what
       | you've scanned and lets you export (to CSV, among others). The
       | app is free on both iPhone and Android (there is a paid version,
       | don't know what extras it has or if it's just ad-free), but may
       | want to verify how much history gets stored before you go scan-
       | crazy.
       | 
       | From a US perspective (may apply elsewhere), for books published
       | relatively recently (within the last ~20 years or so), the ISBN
       | is often part of the barcode on the back of the book (ISBN-13s
       | (the updated standard) start with 978, so this is a good clue
       | that the barcode is an ISBN). For a period of time prior to that
       | (and perhaps still applicable to Mass Market Paperbacks), there
       | is a barcode on the back that is NOT an ISBN, but there is an
       | ISBN barcode on the inside front cover. I've not discovered any
       | systematic way to pull an ISBN out of a non-ISBN barcode (though
       | I haven't dug too far -- my collection hasn't reached 4 digits
       | yet and I've been happy to type when scanning wasn't an option).
       | 
       | Once you have the ISBNs, I like to query against the Open Library
       | API [2], which is a part of the Internet Archive. The information
       | in there is fairly robust, if inconsistent (the capitalization of
       | titles is sometimes as printed on the title page, sometimes
       | Library of Congress format, other minor things). They have a lot
       | of data points available, such as cross-referenced IDs with
       | Goodreads and LibraryThing, but again, this is community-
       | supported data, so YMMV as to completeness or accuracy.
       | 
       | Another note -- many books have _separate_ ISBNs for hardcover
       | editions, trade paperback editions, mass market editions, eBooks,
       | etc (and sometimes don 't have an ISBN at all for things like
       | Book of the Month Club editions). I don't know if this is a
       | requirement, or a luxury that big publishers have, but it is
       | something I've noticed (you'll sometimes see multiple ISBNs
       | listed on the copyright page, along with their formats -- also
       | you may see related editions on Indiebound [3], along with their
       | ISBNs). A cursory glance at Open Library doesn't seem to have a
       | data point distinction for this (which is unfortunate), so you
       | may still have to note this, but _theoretically_ it may be
       | possible to get this information from the ISBN directly at some
       | point.
       | 
       | Source for ^^: I read a lot, have a lot of books, briefly ran a
       | (failed) specialized online bookstore, and wrote a CLI tool [4]
       | for myself to solve this very issue.

       | I had a gig doing this once in grad school. Here's my method. It
       | worked great:
       | 
       | First, close the library (or library section) until your work is
       | complete. It's critical that the books not go wandering or get
       | rearranged during this process.
       | 
       | Next, grab an SLR (or equivalent mirrorless) camera with video
       | mode. Set it to video mode. In good lighting, play it over the
       | shelves, one by one, from left to right. Slowly.
       | 
       | Make sure the spines are all legible. This is your set-of-books.
       | 
       | Set yourself or someone else up transcribing the titles from the
       | recording, in the order shelved. Check it a couple of times. If
       | you missed a book, or couldn't read the spine from the recording,
       | add it here.
       | 
       | Once you are certain your list is accurate and complete, print
       | (or put on your phone) the list of books. (Still in the order
       | shelved.)
       | 
       | Now, again, working top-down, left-to-right, take books out in
       | sets of eight. (I like eight because it's a nice round number,
       | it's near miller's magic number, and it's also a number of books
       | I can typically carry.)
       | 
       | For each 'byte' of eight books, take your SLR and, in photo mode,
       | take a pic of the frontmatter page of that book -- the one
       | containing the date of publication, and, most critically, the
       | ISBN.
       | 
       | Put the eight books back on the shelf and take another eight.
       | Repeat until complete. Be sure not to miss a book.
       | 
       | Now you have a list of books and a set of pics. Guess what? They
       | are the same length and in the same order. So, book 1 on your
       | list is the first pic on your SLR. And so on.
       | 
       | Now, you can OCR those pics for the ISBN. As backup/redundancy
       | you can grab other info as well, e.g. publisher, etc. to sanity-
       | check the results of your ISBN lookup.
       | 
       | Congratulations, you now have enough information -- a title and
       | and ISBN -- for e.g. Google Books to pull up the rest of the
       | info, which you can sanity check against the other deets you
       | OCRed out of the frontmatter page.
       | 
       | Final tip: Calibre has a book information lookup thingy; it
       | wasn't what I used back in the day, but AFAIK it should work
       | great. It may be possible for you to simply populate the Calibre
       | book list with titles and ISBNs, and have it just magically whisk
       | other details -- date of publication etc. -- into the appropriate
       | fields. Again, you can cross-check these (either exhaustively or
       | spot-check) against the OCRed contents of the frontmatter pages,
       | which (again) you associated with a book title in the initial
       | step.
       | 
       | Happy librarianing!

         | just bought a 2nd (or 3rd) copy.

         | 2. Insurance purposes. If I had a fire or something I imagine I

         | process.
         | 
         | 3. Related to (2), but if I had to replace a substantial
         | portion of my library, it would help if I had the items in the
         | library cataloged.
         | 
         | 4. Locating books. I have enough books jammed into my apartment
         | that I sometimes struggle to locate a particular one. Or even
         | remember if I own a particular title at all or not (see (1)
         | above). A catalog, with notes like "In living room, on bookcase
         | A, shelf 2" or "in office, bookcase Q, shelf 4" would be a huge
         | benefit at times. Even more so for the handful that would fall

       | made in China and sold on EBay. I have played around with those
       | and find that they read barcodes when they feel like reading
       | barcodes and it is quicker to type the codes in.

         | There's a certain rare, out-of-print book that took me a couple

         | one is that it came from the same speciality publisher. Every
         | time I found a copy of the rare book on various used book
         | websites, the common one showed up on my porch instead.

         | was actually sent went for $15 used really made returns
         | difficult.
         | 
         | My search finally ended when a copy showed up on eBay, complete

         | I'm not OP, but I also have thousands of books (a little over
         | 4100 at last count), so I guess my answers might be of
         | interest.
         | 
         | 1. I'm about 50 years old. (The furthest back my records go is
         | 2004, when I was about 35 and the count was about 2300.)
         | 
         | 2. Of the 4100 books in my catalogue (it's a CSV file, very
         | high-tech), 1233 are fiction. Rough counts for some non-fiction
         | subject areas: science 520, mathematics 420, philosophy 250,
         | computing 220. Others with substantial numbers: religion 270
         | (I'm not religious, but I used to be and my wife still is),
         | humour 240, history 210, children's books 180 (may be wrong; we
         | don't always bother to record these and sometimes we get rid of
         | them since children grow), reference works 110 (dictionaries,
         | encyclopaedias, etc.), music 100, puzzles 100, poetry 100,
         | language 100, books of essays 100, cookery 100 (these are
         | mostly actual cookery books, which maybe don't really belong in
         | the same list), biography 90, literature 90 (meaning literary
         | criticism, books about books, that sort of thing; actual works
         | of literature are mostly under "fiction"), politics 80,
         | autobiography 75 ("biography" earlier excludes these), games 65
         | (this is things like chess books, not books that are somehow
         | also games), education 65.
         | 
         | 3. I think about 10% of the books are unread at any given time.
