{"description": {"type": "/type/text", "value": "Four software designers present a catalog of simple and succinct solutions to commonly occurring design problems, using Smalltalk and C++ in example code. These 23 patterns allow designers to create more flexible, elegant, and ultimately reusable designs without having to rediscover the design solutions themselves. The authors begin by describing what patterns are and how they can help you design object-oriented software. They go on to systematically name, explain, evaluate, and catalog recurring designs in object-oriented systems.--From publisher description."}, "identifiers": {"librarything": ["3985"], "goodreads": ["85009"], "wikidata": ["Q126543992"]}, "title": "Design Patterns", "subtitle": "Elements of Reusable Object-Oriented Software (Addison-Wesley Professional Computing Series)", "authors": [{"key": "/authors/OL1515521A"}, {"key": "/authors/OL1289741A"}, {"key": "/authors/OL2670757A"}, {"key": "/authors/OL225901A"}], "publish_date": "January 15, 1995", "publishers": ["Addison-Wesley Professional"], "table_of_contents": [{"level": 0, "label": "", "title": "Preface", "pagenum": "xi"}, {"level": 0, "label": "", "title": "Foreward", "pagenum": "xiii"}, {"level": 0, "label": "", "title": "Guide to Readers", "pagenum": "xv"}, {"level": 0, "label": "1", "title": "Introduction", "pagenum": "1"}, {"level": 0, "label": "1.1", "title": "What is a Design Pattern", "pagenum": "2"}, {"level": 0, "label": "1.2", "title": "Design Patterns in Smalltalk MVC", "pagenum": "4"}, {"level": 0, "label": "1.3", "title": "Describing Design Patterns", "pagenum": "6"}, {"level": 0, "label": "1.4", "title": "The Catalog of Design Patterns", "pagenum": "8"}, {"level": 0, "label": "1.5", "title": "Organizing the Catalog", "pagenum": "9"}, {"level": 0, "label": "1.6", "title": "How Design Patterns Solve Design", "pagenum": ""}], "covers": [10827044, -1], "source_records": ["marc:OpenLibraries-Trent-MARCs/lbrn.mrc:3013169:967", "ia:designpatternsel00egam_450", "ia:designpatternsel00gamm_004", "ia:designpatternsel00gamm_459", "ia:designpatternsel00gamm_469", "ia:designpatternsel00gamm_780", "marc:marc_openlibraries_sanfranciscopubliclibrary/sfpl_chq_2018_12_24_run05.mrc:422328825:4348", "bwb:9780201633610", "marc:marc_loc_2016/BooksAll.2016.part23.utf8:142755284:847", "marc:harvard_bibliographic_metadata/ab.bib.12.20150123.full.mrc:206480810:857", "idb:9780201633610", "marc:marc_columbia/Columbia-extract-20221130-004.mrc:280910212:4325", "marc:harvard_bibliographic_metadata/20220215_020.bib.mrc:191450274:4307"], "languages": [{"key": "/languages/eng"}], "local_id": ["urn:trent:   94034264 //r98", "urn:trent:0116405842158", "urn:sfpl:31223118833954", "urn:sfpl:31223118833962"], "type": {"key": "/type/edition"}, "ocaid": "designpatternsel00egam_450", "isbn_10": ["0201633612"], "isbn_13": ["9780201633610"], "lccn": ["94034264"], "lc_classifications": ["QA76.64 .D47 1995", "QA76.64.D47 1995"], "oclc_numbers": ["501190421", "31171684"], "key": "/books/OL7408317M", "number_of_pages": 395, "works": [{"key": "/works/OL6030812W"}], "latest_revision": 34, "revision": 34, "created": {"type": "/type/datetime", "value": "2008-04-29T13:35:46.876380"}, "last_modified": {"type": "/type/datetime", "value": "2025-10-30T17:33:24.191338"}}
