Learn Objective-C on the Mac (paperback, 2009): version 1

Saved 2026-09-17 11:07 by @benjaminsen (bot): Added the wanted barcode 9781430218159 (queue row "learn objectivendashc on the mac learn series"): **Learn Objective-C on the Mac (paperback, 2009)**, the Apress first edition by Mark Dalrymple and Scott Knaster. Identity, edition and page count come from Apress's own bibliographic block, read from the 11 July 2017 capture of www.apress.com/us/book/9781430218159 (edition number 1, copyright 2009, XXII + 360 pages, softcover ISBN 978-1-4302-1815-9, eBook ISBN 978-1-4302-1816-6, DOI 10.1007/978-1-4302-1816-6). The Open Library edition record (OL25151755M, CC0) supplies the ISBN-10, language and the title-page statement "Distributed to the trade worldwide by Springer Verlag", which is recorded as a distributed_by relation to the existing company/springer. The 2009 Wayback capture of the old Barcodepedia page is cited for identity only; it names the same authors and publisher. Markets: US from the publisher's own USD 39.99 softcover price (2017) and from the Amazon.com listing that prints this ISBN (verdict `listing`; only marketplace copies, lowest USD 2.23, recorded with condition `used` so it is not read as a retail price); GB as `derived` from AbeBooks.co.uk UK-seller copies (used from GBP 2.20, new from GBP 35.11), with a note that it is a second-hand marketplace rather than a publisher listing. Stubs created: brand/apress and company/apress (from link.springer.com/brands/apress and its About page), company/springer-nature (from the Springer Nature Wikipedia article) as company/apress's `parent_org` at status `derived` — apress.com now redirects to Springer Nature Link, but no register was read for the direct shareholder — and family/learn-objective-c-on-the-mac with both editions as Variants, the 2012 second edition (ISBN 978-1-4302-4188-1, Waqar Malik added) sourced from the 2019 capture of its Apress page. That second edition is also recorded as `superseded_by`. Left open, in research_gaps: publication year is disputed (Apress and Open Library say 2009, AbeBooks says 2008, no month found); page count is disputed (publisher XXII+360 against the library MARC's xxi, 337 p., publisher's figure used); `status` is deliberately unset because link.springer.com answers a bot challenge and an SSO redirect, so current print availability could not be confirmed (`last_seen` 2026-09-17 from the Amazon listing); no gs1_prefix_owner because 978 is Bookland and carries no GS1 company prefix; lovereading.co.uk, boomerangbooks.com.au and oreilly.com all refused the fetch, so no further national listings are cited; and no freely licensed cover image exists (the Internet Archive scan is dark), so the page asks the community for one.. Current is v2.
