| 23skidoo 1st Oct 2020 | Q.V. for the retitled later edition. | |
| ppint. 3rd Jan 2018 | the sbn-9 which preceded the isbn-10, was later converted to an isbn-10 by prepending a zero - if the number was still in use, that is. doing this ensured the checksum digit did not change. since then, publishing in the english language has expanded to such an extent that the isbn-10s allocated to english now include those commencing with a "1" as well as a "0". isbn-10s were converted into isbn-13s (again, if the number was still in use) by prepending the three digits "978" to the isbn-10, which necessarily changes that final checksum digit. for a while, some in-print books will continue to bear only an isbn-10, some both isbn-10 and isbn-13, and some only an isbn-13. there was - fairly briefly - an abn, or american book number. the three-digit abn publisher numbers allocated overlapped with - i.e. were not compatible with, or at least were not necessarily compatible with - those of the sbn-9 and isbn-10 system. yr hmbl srppnt. does not recall ever seeing an abn with a checksum digit. bar-code numbers on books are not necessarily anything to do with the isbn system, though the isbn(-10) or isbn-13 may be printed close to it. american usage especially early on was erratic, even allowing for the fact that most of the first element often indicates the distributor rather than the publisher: the rest of the first element often indicates the u.s. cover price, with the publisher's cat# for the particular book relegated to a separate, second block of bar-coding. usage should (eventually) unify upon the first and largest bar-code (& bar-code number) block on books using 978- indicating ''books''; the next part of the number-string identifying the language (''0'' or ''1'' = english language); the next part identifying the publisher; the next part identifying the specific book (often the particular printing); finally the checksum digit (with both sbn & isbn(-10) systems, this can be used to spot accidental transpositions of digits, as well as incorrect digits and other mistakes; the isbn-13 check digits are calculated according to a different system, and cannot reveal transpositions). if the cover price is indicated it should be in a second, smaller block of bar-code & numbers and given in the smallest currency unit (e.g. in pence or cents, not in pounds nor dollars) prepended by as many zeros as are needed to give a five digit block (e.g. ''00899'' = £8.99 or $8.99 depending on local currency); this seems to now be being indicated as such a price indicator by being prefixed with ''9'', and ''900000'' being used to indicate ''this block is not being used on this book''. (e.g. ''902295'' = £22.95 or $22.95 depending on local currency) | |
| Scratchy45 10th Nov 2015 | The ISBN (originally 10 digits, then expanded to 13 digits) ends with a check digit - which has nothing whatsoever to do with the edition but is calculated using the preceding digits. Randomly googled explanation here I became very familiar with the 10-digit ISBN and its uses and misuses during a dozen or so years working firstly in bibliographic information and then selling books.I'll gladly post a general explanation of the elements of an ISBN if anyone should want it - or if it's needed given the existence of links like the one above. Nowadays there may be a sequence of numbers on the the inside page of a book where bibliographic and copyright information is recorded. This identifies the reprint number for that book. | |
| Auto_Da_Fe 8th Nov 2015 | Doesn't seem to be true (or at least always true). I've just had a look at a dozen or so first editions. About half did end in zero, but there were also a 5 a 6 and a few 8s. It could explain why some ISBNs end in an X though, (past the 9th edition?) | |
| gregs45s SUBS 7th Nov 2015 | I'm not sure of the year here,so have added a scan with the ISBN etc.Does anyone know if there is any truth in what i've been told,that the last digit of the ISBN number indicates the edition?,well i was actualy told that 0 = First Edition,1= Second,2 = Third,any truth in that?,or is that all rubbish?Which i suppose would make this a third edition? | |
