    Although there are many good, reliable books that are several years old (on computer principles, logical logic and whatnot), you'll probably be better off sorting by year.

    You'll end up putting a few great books farther down the line than you otherwise would, but sorting by publication date will ensure that the vast majority of the books are still relevant.

    If you've got time, sort by quality. You're the expert, though, and your time is limited. Would you prefer something that is good enough - and done, or something that's perfect ... but not available.

      I might add, for the questionable books, put them in a box and list them on one of the online auctions for cheep or something- buyer pays shipping. There might be an admin out there that inherited something old and needs reference material or perhaps a kid getting a hand me down system and wants to make use of it.

      Applications (Office, Photoshop, etc) have a very short shelve life. Anything over a couple of years old is useless.
      Languages (Perl, PHP, Ruby); throw away after a decade or so. It differs though; old C books may still apply, old Java books less so.

      Books can provide a nice "all inclusive" feeling for a broad topic, or even a specific one. There are lots of great online resources, but most are limited in scope, and learning that way can have a piecemeal feeling to it. Sometimes it's nice to have a topic covered from a starting point to an ending point by the same author(s) and in a consistent style.

      Good example would be "Programming Perl". Sure, you can learn perl in pieces from the gazillion online resources (perlmonks is awesome), but if you read the book cover to cover, you get a kind of well thought out guided path through the language. Personally I've still got my (second edition) copy and occasionally dig it out... it's aged well and makes a great resource.

If your answer is anything other than "okay I was exaggerating" you are weird. Seriously, most people don't keep books on the desktop or in a folder that is always visible.

      If I had to plug in an external drive or DVD, wait for it to spin up, browse to the folder, find the file, and wait for the PDF reader to open up, I would open the book. I can make things sound more complicated than they really are to make my point sound more convincing.

    I used to work at a used bookstore, and I was in charge of our computer books section. My experience was that programming books would sell the best - I would put them on the shelf, no matter how old they were, and they would sell. You'd be surprised to see that some still look up for $10-20 on Amazon too, even at over 10 years old. Java & C/C++ sold the best, but they would all sell, I always had empty room on those shelves. The next best sellers were database/server books, then recent Windows OS/recentish OS X/any Linux books. Older OS books (especially older Windows books), most application books, and most how-to-use-a-computer/internet/laptop/etc books did not sell well unless they were less than a year old.

    So I would have also rescued your two books - I think they were good choices, and are likely to sell even though they are old. I would use the above criteria for determining what to keep, and if space is an issue, I'd limit some of the OS/application/textbook sort of stuff to 2-3 years back instead of 5 rather than get rid of older programming & server/database books.

    I contacted some author and almost everyone wants to release the content of their books for free, but this can not be possible since the copyright of the books belongs to the publishers.

    The publishers are big companies and you don't even know to whom ask permission for this and some of them don't want to give anything from their IP. (I even tried once with MS Press by Twitter and never got an answer).

    Do we have to wait a 100 (or something like that) years for the content to be public domain? or does anybody knows any trick on some publishers to open some of their content?

      There's nothing to be done about old books. What authors can do is work clauses like this into their publishing contract, now, for new books that are written. From practical experience trying that, it's extremely hard to do that if you're an unpublished author. But if you've had a successful book already, it's possible to leverage that into future books eventually being available under a free license.

      Since quite a bit of the computing book market is constantly being rewritten to stay current, if enough a

  • On the one hand, RIP 'cause they're obsolete. On the other hand, there's a lot of obsolete stuff still in use that will be in use for a long time. The trick is getting those obsolete books to the people maintaining those obsolete systems. The chances of someone needing a 90s reference book that you have walking into your bookstore are pretty slim. Maybe you can list them on ebay.

    The APPLE II BASIC programming manual by Jef Raskin currently goes for $52 and up on Amazon. A few years ago I found a late-'90s book on embedded systems programming that turned out to be in demand and later sold for about $100 on Amazon. So look up anything unusual, specific, or that might have nostalgia value there or on Bookfinder.com before you recycle them or sell them for a buck or two.

      There's someone in my workplace still using the copy of the "Fortran cookbook" that I picked up second hand in 1987.

      Also keep an eye out for BIOS Disassembly Ninjutsu Uncovered by Darmawan Salihun. People are asking $1500 for it on Amazon since it's out of print. I guess it's a collector's item. The company I used to work for paid $700 for it on amazon 6 months ago and as soon as I heard that I googled the book to see why it was in such demand and discovered it was out of print and the author had even posted a PDF of the book on his blog. So, there was no reason to even buy it for the information; it's only worthwhile bu

        Despite what you think, all of what you say is funny.

        Some of it is funny ha-ha, and the rest is funny-queer.

      As the number of books for a title go down some software, be it amazon or the sellers, automaticcly increases the prices. So for that book there could just not be many people selling it.
      When you get a book like that the best place to check is ebay. When I was recently throwing out my old books I had a few books that amazon placed in the $100 range and ebay had a bunch at $.10; did not think that a 3rd edition of a management book that was currently near edition 20 would be of that much value.
  • If it's for either the current version of a technology or is for a technology that is version free - keep it. e.g. The Data compression book [amazon.co.uk], and The Pragmatic Programmer are both 15 years old but are still great books that people could learn a lot from.

    If it's for a technology that has had a newer version (or versions) released - probably bin it. Even a book a couple of years old will be massively out of for technologies that are advancing rapidly. e.g. a book on how to develop for iPhones that was release

  • In the desert in Tucson, there's a massive airplane graveyard, where you can always go to find a part. I collect these used books in my business, and it's very frustrating. You can't afford to keep them in a rent-paying, heated building. But they always eventually go up in value. The solution is "speculative accumulation". Find a place in the desert, where they won't mold (they will anywhere else, unfortunately). And dig them up in 100 years. Look at what Kaypros and IBM 85 series monitors are sel
  • Hi g01d4,
    Have a look at any good bookshop with a 'computing' section. Computer graphics and fundamental CS/math education books seem to have a few extra years in them.
    Programming languages, mobile related, tax, product guides seem to have a life under a year with massive version drift.

    1. I keep most programming books, in fact I still have 8086 assembly and qbasic on my shelf. My rational is they are as useable today as they were twenty years ago. However, books like HTML3 were recycled years ago.

    2. Technical books get recycled after ten years. I.e. Windows 95 for retards, Ethernet the definitive guide, Astrisk, CNE study guide, Master Fedora 3, Absolute FreeBSD. However, a book like "The Design and Implementation of the FreeBSD Operating System" would be kept as it is a reference book ooperating system design... which fundamentally hasn't changed in thirty years.

    3. I unconditionally keep all math, chem, electronics, science type reference books. It's not as if the laws do the universe are going to change anytime soon.

    Basically, open the book up to a random section, if it is still relevant (I.e. calculus, electronics principles, x86 assembly programming, c programming, perl cookbook, etc.) keep it.

  • I think the less than 5 years is good for a useful computer book for the most part. There are a few folks who may want the older stuff for legacy systems, or things that are institutions (such as vi or EMACS) that will likely be around forever that it gives a good baseline on.

    However, there are a few cases where the book may be more of interest from a collectable/historical perspective. I have a battered copy of Programming Perl, with a copyright date of 1991--it has the pink spine. About ten years ago, I

  • Like "The art of software testing" from 1976. Or the C programming language by Kerningham and Richie. I would certainly save the classics.
  • By year is probably the most efficient way to filter. I would however split the lot between Theory, Syntax, and Technology. The former will have far longer relevance and the latter will have the least with the passing of time. Theory can last for decades, but technology is constantly overturning and starts to become irrelevant even a couple years after print.
